Nitrogen-doped graphene (NRGO) can activate peroxymonosulfate (PMS). However, the activation mechanism of PMS by NRGO needs to be further investigated. In this study NRGO was prepared by a facile method, and its activation mechanism of PMS for the degradation of sulfamethoxazole (SMX) was investigated. The XPS spectrum showed that nitrogen loading reached 16.5% (atomic percentage). The SMX removal efficiency reached 91.7% at 240 min in the NRGO-activated PMS system. During the PMS activation process, NRGO acted as dual roles: PMS activator and electron transfer mediator. NRGO can activate PMS to form singlet oxygen. In addition, NRGO can act as the electron transfer mediator to enhance the SMX degradation. Density functional theory (DFT) calculations demonstrated that nitrogen doping increased the charge density of net positive carbon atoms and decreased the energy gap, further enhancing the PMS activation. The effects of pH, temperature and the concentrations of chloridion and humic acid were investigated. NRGO had good stability in activating PMS evidenced by the cycling experiments. Eight degradation intermediate products of SMX was identified. Among them, 3-amino-5-methyl-isoxazole and 4-nitro-SMX presented high abundance. The acute toxicity of treated SMX solution increased, suggesting that the degradation products of SMX formed in the non-radicals? process should be concerned. This study provided an insight into the SMX degradation by NRGO-activated PMS including the mechanisms of PMS activation and SMX degradation.

Reference of 33282-15-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 33282-15-4, 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid, introducing its new discovery.

4-Cyanobenzenesulfonamides of secondary amines were found to cleave to the parent amine cleanly under the action of thiol and base. This feature readily lends itself to the use of this motif as an amine protecting/activating group within a broader context of amine synthesis. The crystalline sulfonamides could be further elaborated by alkylation and arylation similarly to nitrobenzenesulfonamides. The sulfonamides could withstand conditions that functionalize nitroarenes, such as reductions and vicarious nucleophilic substitution reactions.

In this paper, a regioselective, efficient and convenient synthesis of 2-aminobenzophenones through acylation of anilines with alpha-oxocarboxylic acids assisted by tert-butyl nitrite is presented. Interestingly, tert-butyl nitrite acts as not only an efficient and mild nitrosation reagent, but also a sustainable oxidant required in the Pd(ii)-catalyzed decarboxylative acylation. Meanwhile, the NO unit turned out to be an easily introduced and readily removable directing group for the regioselective acylation.

Tetranuclear Fe clusters have been synthesized bearing a terminal FeIII-oxo center stabilized by hydrogen-bonding interactions from pendant (tert-butylamino)pyrazolate ligands. This motif was supported in multiple Fe oxidation states, ranging from [FeII2FeIII2] to [FeIII4]; two oxidation states were structurally characterized by single-crystal X-ray diffraction. The reactivity of the FeIII-oxo center in proton-coupled electron transfer with X-H (X = C, O) bonds of various strengths was studied in conjunction with analysis of thermodynamic square schemes of the cluster oxidation states. These results demonstrate the important role of distal metal centers in modulating the reactivity of a terminal metal-oxo.
