Tributyltin radicals have been allowed to react with erythro- and threo-2-bromo-3-(phenylsulfonyl)butane (5a,b) to generate β-(phenylsulfonyl)-sec-butyl radicals 9.The intermediate 9 eliminates phenylsulfonyl radicals to form 2-butenes in a nonstereospecific manner.The lack of stereospecificity is due to rotation about the C2-C3 bond before the loss of the phenylsulfonyl radical can occur and implies that the stabilization of the radical by sulfur bridging is negligible.
Neighboring Group Participation in the Oxidation of Hydroxy Sulfides. Control of the Reaction Courses and Products

Oxidation of the hydroxy sulfides with hexabutyldistannoxane (HBD)-bromine system was studied in order to clarify neighboring group participation during the course of reaction.The oxidation products were found to be highly dependent on
