Oxidations of 2,2-dialkyl and spiro with lead tetraacetate gave mainly sulfoxides and disulfoxides.The stereochemistry of these products was elucidated by n.m.r. spectroscopy.Oxidation of 2-methyl-2-aryl derivatives gave sulfoxides as minor products; here the main products were derived from attack on the methyl group forming acetoxy, diacetoxy, formyl and carboxylic acid derivatives and ring cleavage products. 2,2-Diaryl derivatives also formed small amounts of sulfoxides but ring cleavage products were predominant.Monosubstituted benzodithioles were very reactive and produced a variety of oxidation products, mostly unidentified.
