Oxidative dimerization of (hetero)aromatic amines utilizing t-BuOI leading to (hetero)aromatic azo compounds: Scope and mechanistic studies

A straightforward synthetic method of both symmetric and unsymmetric aromatic azo compounds through an efficient and cross-selective oxidative dimerization of aromatic amines using tert-butyl hypoiodite (t-BuOI) under metal-free and mild conditions has been developed. This method was also found applicable to the synthesis of heteroaromatic azo compounds. The spectroscopic study indicates the involvement of N,N-diiodoanilines in the oxidative reaction as the key intermediate.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 5-Methylisoxazol-3-amine, you can also check out more blogs about1072-67-9

Effects of water environmental factors on the photocatalytic degradation of sulfamethoxazole by AgI/UiO-66 composite under visible light irradiation

It is necessary to find visible light responsive photocatalysts for rapid and simple degradation of organic pollutants in water environment. In this work, a visible light responsive composite photocatalyst AgI/UiO-66 was prepared by an in situ growth method. Sulfamethoxazole (SMZ) antibiotic was selected as the target contaminant to probe the photocatalytic performance of the as-prepared AgI/UiO-66 composite under visible light irradiation. The results showed that the photocatalytic performance of the AgI/UiO-66 composite enhanced significantly compared to pure AgI. The effects of typical environment factors (i.e. pH, inorganic salt ions and common anions) on the degradation of SMZ were evaluated extensively. Results showed that the investigated pH (5.2, 7.0, 9.5) had no apparent effect on the photocatalytic degradation of SMZ except pH 2.5, at which the degradation rate of SMZ decreased significantly. In addition, inorganic salt ions and Cl?, HCO3? and SO42? anions in water exhibited no apparent effect on the degradation of SMZ. The effect of water matrix on the degradation of SMZ was also investigated. In the river water, the removal efficiency of SMZ was reduced compared with the cleaner water matrix. The capture experiments of radicals confirmed that superoxide radicals ([rad]O2?) and hydroxyl radicals ([rad]OH) were the main active species for the photocatalytic degradation of SMZ in the present work. Finally, the tentative degradation pathways of SMZ were proposed based on the intermediates analysis.

Detoxification and degradation of sulfamethoxazole by soybean peroxidase and UV?+?H2O2 remediation approaches

Development of efficient methods for the degradation of emerging pollutants such as pharmaceuticals and pesticides are being recognized as a research priority as more and more of these organic pollutants are being detected in our water bodies. In this work, the degradation of the emerging pollutant sulfamethoxazole (SMX) was carried out using a soybean peroxidase (SBP) enzyme system and an advanced oxidation process (UV + H2O2). The optimized conditions for sulfamethoxazole degradation by the peroxidase enzyme showed an absolute requirement for a redox mediator (1-hydroxybenzotriazole) and low pH. The other conditions for an efficient degradation were as follows: [H2O2] = 56 muM, [SBP] = 78 nM and [SMX] = 5 ppm. The degradation of the pollutant was followed using UV?Vis spectrophotometry and liquid chromatography?mass spectroscopy (LC?MS). The formed products were identified using liquid chromatography?tandem mass spectrometry. The two remediation methods, an enzymatic approach using SBP + H2O2, and the photolytic technique using UV + H2O2, generated diverse sets of intermediates, suggesting that different degradation routes were at work in the two systems. Phytotoxicity studies carried out using Lactuca sativa (lettuce) showed different levels of detoxification of the SMX pollutant after the two different remediation treatments.

Herbicidal activity and molecular docking study of novel accase inhibitors

Acetyl-CoA carboxylase (ACCase) is an important target enzyme for the development of new bleaching herbicides. On the basis of structure-activity relationships and active subunit combinations, a series of novel 2-phenyl-3-cyclohexanedione enol ester derivatives was designed and synthesized by coupling and acylation reactions. The preliminary biological tests indicated good post-emergent herbicidal activity at a dosage of 150?300 g ai/ha, superior to that of clethodim against barnyard grass. Compound 3d was safe with respect to maize, even at a dosage of 300 g ai/ha. Compound 3d showed the best ACCase inhibitory activity in vitro, with a value of 0.061 nmol h-1 mg-1 protein, superior to that of clethodim. Molecular docking modeling showed that compound 3d and clethodim had the same interactions with surrounding residues, leading to an excellent combination with the active pocket of ACCase. That may have been the mechanism responsible for the death of the barnyard grass. The present work suggests compound 3d as a potential lead structure for further development of novel ACCase inhibitors.

Lanthanides and actinides: Annual survey of their organometallic chemistry covering the year 2018

This review summarizes the progress in organo-f-element chemistry during the year 2018. A continuing trend for many years, which remained important in 2018, was the synthesis and investigation of reactive trivalent lanthanide mono- and bis(alkyl) or (benzyl) complexes supported by a variety of non-cyclopentadienyl ligands such as amidinates, beta-diketiminates or NHC ligands. An important contribution was the synthesis of the homoleptic, solvent-free dibenzyl complexes [Ln(CH2Ph)2]n (Ln = Eu, Sm, Yb) which served as precursors for the synthesis of the first divalent lanthanide imides [(THF)Ln(mu3-NDipp)]4. Lanthanide carbene chemistry has also been of growing interest. Functionalized NHC ligands were employed to unveil new reactivity as demonstrated in the synthesis of homoleptic lanthanide complexes with aryloxide-tethered NHC ligands, Ln(LR)3 (LR = 2-O-3,5-tBu2C6H2(1-C{N(CH)2N(R)}), R = iPr, tBu, Mes), which reacted with CO2 by selective insertion into Ln?C(NHC) bonds. A diverse reactivity towards small unsaturated molecules was observed for phosphino and thiophosphinoyl alkylidene lanthanide complexes as well as for phosphinidene lanthanide complexes. Furthermore, the trinuclear mixed oxo/alkyl complexes L1 3Ln3(mu2-CH3)3(mu3-CH3)(mu3-O) (with L1 = PhC(NC6H3 iPr2-2,6)2; Ln = Sc, Y, Lu, Dy) undergo non-redox oxygen transfer with PhNCS or CS2 despite the presence of reactive Ln-alkyl bonds. The synthesis of pseudo-Grignard reagents PhLnI (Ln = Eu, Yb) was investigated and their synthetic potential in organometallic chemistry demonstrated. The first lanthanide-cyclobutadienyl complexes were obtained as anionic ?tuck-in? complexes [M{eta4-C4(SiMe3)4}{eta4-C4(SiMe3)3-kappa-(CH2SiMe2)}]2? (Ln = Y, Dy), showing square-shaped cyclobutadienyl ligands. Further progress has been made in the understanding of ?new? divalent lanthanide chemistry, especially the influence of the ligand size. The small CpMe ligand formed highly reactive complexes, e.g. [K(crypt)][Y(CpMe)3], with the larger lanthanides, which reacted with the solvent to give unprecedented reductive THF-ring opening. However, with smaller lanthanides the complexes [(18-crown-6)K(mu-CpMe)K(18-crown-6)][CpMe 3Ln] (Ln = Tb, Ho), displaying an inverse sandwich as counter-cation, could be isolated. The reactivity of the highly bulky complex SmCpAr-Et 2 (CpAr-Et = C5(4-EtC6H4)5) towards a large range of small molecules was investigated, revealing only reaction with cuminil to afford the first trivalent lanthanide decaaryllanthanidocene complex SmCpAr-Et 2(Ar?C(O)C(O)Ar?) (Ar? = 4-iPrC6H4). Following the important discovery of recent years on SMM (single molecule magnet) behavior of Dy metallocenes, the quest for even better SMMs continued in 2018. Several new record-holding complexes were synthesized based on polyisopropyl-cyclopentadienyl complexes, with the best complex to date being [(C5 iPr5)(C5Me5)Dy] [BAr4], showing magnetic hysteresis up to 80 K and an effective energy barrier to reversal of magnetization Ueff = 1541 cm?1. Several remarkable lanthanide arene complexes have been prepared and structurally characterized. For example, the bimetallic inverse sandwich La2+ complex salt [K(18-crown-6)(THF)2][(Cp?2La)2(mu-eta6:eta6-C6H6)]¡¤THF (Cp? = C5H3(SiMe3)2-1,3) reduces hydrocarbons such as naphthalene, anthracene, or cyclooctatetraene to give La3+ complexes of the hydrocarbon anions. Samarium-arene bonding has also been observed in the rare samarium(II) aryloxide Sm(OAri Pr6)2 [Ari Pr6 = ?C6H3-2,6-(C6H2-2,4,6-iPr3)2] and in the remarkable tetranuclear samarium(II) inverse sandwich complex (mu-eta6:eta6-C7H8)[KSmL3]2 (L = OSi(OtBu)3). Several new triple-decker complexes of the type Ln2(COT?)3 (COT? = bis(trimethylsilyl)cyclooctatetraenyl dianion) have been isolated and structurally characterized. The synthesis and structural characterization of four unsolvated divalent lanthanide cyclononatetraenyl sandwich complexes, Ln(Cnt)2 (Ln = Sm, Eu, Tm, Yb; Cnt = eta9-cyclononatetraenyl) have also been achieved. Single-crystal X-ray diffraction studies revealed that these neutral sandwich complexes are rigorously linear. A rare heterobimetallic [1] ferrocenophane terbium(III) complex has been found to exhibit single-ion magnet behavior. Reduction of the scandium precursor Sc(nacnac)(OAr)(OCP) (nacnac? = [ArNC(CH3)]2CH, Ar = 2,6-iPr2C6H3) with KC8 afforded a binuclear scandium complex comprising a unique [OCPPCO]4? central motif formed through P?P radical coupling. Heterobimetallic Sm/Co polyarsenides [(CptttCo)2As4Sm(C5Me4R)2] (Cpttt = 1,2,4-C5H2 tBu3, R = Me, nPr) were synthesized from the reaction of divalent Sm complexes Cp*2Sm, Cp*2Sm(THF)2 or (C5Me4 nPr)2Sm with [(CptttCo)2(mu,eta2:2-As2)2], while the Sm/Sb multimetallic complex [(Cp*2Sm)4(mu4,eta2:2:2:2-Sb8)] was synthesized from the oxidation of Cp*2Sm with activated antimony. The chemistry of endohedral lanthanide metallofullerenes continued to be an active field of research in 2018. Significant achievements…

Exploration of new reaction tools for late-stage functionalization of complex chemicals

Chemistry has always had as a target the conversion of molecules into valuable materials. Nevertheless, the aim of past synthesis has primarily focused on achieving a given transformation, regardless of the environmental impact of the synthetic route. Given the current global situation, the demand for sustainable alternatives has substantially increased. Our group focuses on developing selective chemical transformations that benefit from mild conditions, improved atom economy, and that can make use of renewable feedstocks as starting materials. This account summarizes our work over the past two decades specifically regarding the selective removal, conversion, and addition of functional groups that can, later on, be applied at a late stage for the modification of complex molecules.

Fabrication of Cu2O/Bi25FeO40 nanocomposite and its enhanced photocatalytic mechanism and degradation pathways of sulfamethoxazole

In the study, cuprous oxide (Cu2O) combined with sillenite bismuth ferrite (Bi25FeO40) was successfully fabricated through hydrothermal strategy. Subsequently, physicochemical properties of Cu2O/Bi25FeO40 were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM), N2 adsorption/desorption, X-ray photoelectron spectroscopy measurements (XPS), UV visible diffuse reflectance spectroscopy (DRS). The experimental results indicated that Cu2O/Bi25FeO40 exhibited a significantly enhanced photocatalytic activity, which 85.0% of sulfamethoxazole was decomposed in 120 min under irradiation. Afterwards, scavenger experiments have been carried out to determine the contributions of different species and h+ and H2O2 were manifested to be staple reactive species during the process of sulfamethoxazole (SMX) degradation. In addition, Cu2O/Bi25FeO40 nanocomposite showed good stabilities. And the degradation efficiency of SMX still reached 84.9% after five recycle experiments. Furthermore, some plausible degradation pathways of sulfamethoxazole were detected by a high-performance liquid chromatography-tandem mass spectrometry. Finally, the enhanced visible light photocatalytic mechanism was proposed reasonably. Eventually, this study provides a novel strategy to prepare catalyst which could be potentially applied in emerging pollutants elimination.
