A survey of mononuclear iron(II) complexes with heterocyclic N-donor ligation is presented. A brief introduction to spin-crossover chemistry and low-temperature spin-trapping is provided, since many of these compounds undergo thermal spin-transitions upon cooling or heating. These are highlighted, and the structural changes underlying spin-crossover are discussed where this is known. Materials showing spin-trapping behaviour following thermal quenching or irradiation at very low temperatures are also described.

Molecules containing bridged bicyclic systems, such as the (7- hetero)bicyclo[2.2.1]heptane ring system, are interesting synthetic targets because these systems are present in many molecules with biologically relevant activity. Common precursors for these sytems are the (7-hetero)nobornadienes. This review covers the different approaches used in the last ten years for the synthesis of (7-hetero)norbornadienes through Diels- Alder (D-A) cycloaddition between cyclic dienes and alkynes. The review also shows the synthetic applications of these [2.2.1]bicyclic systems as intermediates in the preparation of other relevant molecules.

Reductive amination (RA) constitutes an attractive and practical strategy for discovering protocols capable of converting biomass into valuable N-containing compounds. Described herein is a versatile and sustainable RA of 5-hydroxymethyl-furfural (HMF), an important biomass-derived aldehyde, using abundant and cheaply available CO and water as reductants. A single phase rutile titania supported gold (Au/TiO2-R) catalyst is shown to efficiently catalyze this CO/H2O-mediated RA under mild and convenient conditions. With this system, a broad spectrum of primary and secondary amines can be used as suitable substrates and the desired reaction can proceed favourably in a highly chemoselective, efficient and atom-economical fashion. In particular, this protocol can also allow convenient access to bis(hydroxylmethylfurfuryl)-amines, a new group of furan-based monomers with great potential to form functional biopolymers with tunable properties. Moreover, this CO-assisted RA is more efficient (higher TON and TOF) and more eco-friendly (increased resource efficiency) than the previous state-of-the-art technique.

(Chemical Equation Presented) A series of N-sulfinyl dienophiles 1c-i has been screened in asymmetric hetero-Diels-Alder reactions using chiral bis(oxazoline)copper(II) and -zinc(II) triflates. The survey pointed out N-sulfine 1c (R = P(=O)(OPh)2) as the most promising N-sulfine regarding yield and stereoselectivity (up to 97% ee). The relative configurations, and in one case the absolute configuration, of the HDA adducts were established by X-ray analysis.

Sulfonamide-based antibiotics are often detected in surface water and secondary wastewater effluent and pose an eminent threat for the development of antibiotic resistance bacteria and genes in aquatic environment. This paper presents the kinetics and stoichiometry of the oxidation of sulfonamides (sulfaguanidine, sulfisoxazole, sulfamethizole, sulfamethoxazole (SMX), sulfamethazine, and sulfadimethoxine) by ferrate(VI) (FeO42-, Fe(VI)) in the acidic to basic pH range (2.0-9.6); apparent second-order rate constants (kapp, M-1s-1) decreased non-linearly with increase in pH. The specific rate constants for the individual Fe(VI) species (H3FeO4+, H2FeO4, HFeO4-, and FeO4-) were determined using acid-base equilibria of Fe(VI) and sulfonamides. The reactivity order of Fe(VI) species with the neutral sulfonamide was H3FeO4+>H2FeO4>HFeO4-, which generally explained the pH dependence behavior of rate constants. Detailed studies regarding the resultant oxidized products (OPs) using liquid chromatography-mass spectrometry/mass spectrometry were performed for oxidation of SMX at different molar ratios of Fe(VI) to SMX (i.e., 1.0-15) and at different pH’s (i.e., 4.0, 7.0, and 9.0); oxidative degradative products include 3-amino-5-methylisoxazole, and hydroxyl-, hydroxylamine-, nitroso-, and nitro-derivatives of SMX. The possible reaction pathways comprise the SN bond cleavage, ring-opening of isoxazole moiety, oxidation of aromatic amine, and the hydroxylation of the benzene ring; different OPs formed under acidic, neutral, and basic pH conditions are described. The value of kapp, 8.9×102M-1s-1 at pH 7.0 suggests the oxidative transformation of SMX in seconds by 1mgL-1 K2FeO4 and interestingly, the removal of SMX could be achieved at neutral pH by Fe(VI) in the presence of humic acid.

Direct monomethylation of primary amines with methyl triflate was achieved with high selectivity (up to 96%). The key point of this single methyl transfer stems from the use of HFIP as the solvent that interferes with amines and avoids overmethylation.

There is growing interest in the use of furans, a class of alternative fuels derived from biomass, as transportation fuels. This paper reviews recent progress in the characterization of its combustion properties. It reviews their production processes, theoretical kinetic explorations and fundamental combustion properties. The theoretical efforts are focused on the mechanistic pathways for furan decomposition and oxidation, as well as the development of detailed chemical kinetic models. The experiments reviewed are mostly concerned with the temporal evolutions of homogeneous reactors and the propagation of laminar flames. The main thrust in homogeneous reactors is to determine global chemical time scales such as ignition delay times. Some studies have adopted a comparative approach to bring out reactivity differences. Chemical kinetic models with varying degrees of predictive success have been established. Experiments have revealed the relative behavior of their combustion. The growing body of literature in this area of combustion chemistry of alternative fuels shows a great potential for these fuels in terms of sustainable production and engine performance. However, these studies raise further questions regarding the chemical interactions of furans with other hydrocarbons. There are also open questions about the toxicity of the byproducts of combustion.

Pergularia daemia is a hispid perennial herb, its latex used in traditional ayurvedic and siddha medicine for migraine, head ache, muscle sprain and swelling sores, boils. Despite of its pain relieving potential, the mechanisms of these effects have yet to be elucidated. The methanolic flavonoids rich Pergularia daemia latex (PDL) extract subjected into particular peripheral and central antinociceptive effects in laboratory animals. The present study was to determine the involvement of nitric oxide (NO)/cyclic guanosine monophosphate (cGMP)/ potassium (K+) channels pathway in the peripheral antinociception induced by flavonoids rich PDL. It was executed systemically for (50, 100 and 200 mg/kg p.o.) to generate dose dependent antinociception when evaluated using acetic acid induced abdominal writhing and formalin test with measured mean IC50 value of 169.9 mg/kg, 136.6 mg/kg and 174.8 mg/kg respectively. PDL at similar doses showed significant dose dependent inhibition of neurogenic pain induced by capsaicin (1.6 g/paw/ IC50 = 194.9 mg/kg) and glutamate (10 mumol/paw/ IC50 = 204.6 mg/kg) which elicits the participation of vanilloid (TRPV) receptors and glutamatergic system. Moreover, PDL displayed reversed antinociception with L-arginine (a NO precursor) (100 mg/kg, s.c.), implying the involvement of L-arginine/nitric oxide pathway besides methylene blue (10 mg/kg, s.c.) remarkably increased the antinociception and an ATP-sensitive K+ channel antagonist glibenclamide (10 mg/kg, i.p.) reversed antinociceptive activity when administered systemically induced by PDL. Conjointly, the results suggested that PDL induced antinociceptive activity was possibly related to inactivate TRPV receptor, glutamatergic system along with the activation of NO/cGMP/ATP sensitive K+ channel pathway.
