Oxidation of thiones to sulphines (thione S-oxides) with N-sulphonyloxaziridines: synthetic and mechanistic aspects
Abstract
The kinetics of the two-step oxidation of diarylthiones by N-sulphonyloxaziridines to sulphines and then to ketones have been investigated and the results compared with those for reactions with perbenzoic acid. The synthetic utility of the oxaziridine and peracid oxidations has been compared for a few aliphatic thiones.
