Abstract

An inexpensive combination of common laboratory reagents, dimethyl sulfoxide (DMSO) and chromatographic neutral alumina, gives an efficient, selective, and high-yielding oxidation of aromatic, aliphatic and alicyclic thiols to the corresponding disulfides in excellent yields under relatively mild conditions.
