Electrochemical Behavior of a Nitrobenzenesulfonyl Derivative of Aniline in Aqueous Solution
نویسندگان
چکیده
O mecanismo de redução do composto N-fenil-4-nitrobenzenosulfonamida foi investigado em meio aquoso por polarografia de corrente direta e pulso diferencial, voltametria cíclica e coulometria a potencial controlado. Em pH < 10, o composto é reduzido em uma única etapa de 4 elétrons. Entretanto duas etapas de redução são verificadas em elevados valores de pH (pH > 11). A redução do grupo ni tro à hidroxilamina na molécula é sempre o processo preponderante no mecanismo eletródico.

The electrochemical reduction of p-nitrobenzenesulfonyl chloride (NBSCl) in dimethylsulfoxide (DMSO) solution is used here as a model to investigate the role of sulfinic acid derivative in this compound’s global reduction process. Cyclic voltammetric experiments reveal the production of sulfinic acid derivative, which is important in chemical reactions involving the original compound and other ...
متن کاملElectrosynthesis of Clozapine Drug Derivative via an EC Electrochemical Mechanism
The fact that oxidation, as one of the main routes of phase I metabolism of drugs, follows by conjugation reactions, and also formation of nitrenium ion as one of the clozapine oxidation products, directed us to investigate the oxidation of clozapine (CLZ) in the presence of nucleophile. The oxidation of clozapine (CLZ) has been studied on a glassy carbon electrode in the absence and presence o...

Electrochemical polymerization of aniline is one of the most promising methods to prepare polyaniline (PANI) materials. However, during this process, the electrolyte solution must be replaced after electropolymerization of a certain time because of the generation and the accumulation of the by-products, which have significant effects on the morphology, purity and properties of PANI products. Tr...
