Abstract

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 intermediates. This
paper also discusses the probable mechanisms of the reduction.
