Vinyl sulfides and vinyl sulfones are ubiquitous structures in organic chemistry because of their presence in natural and biologically active compounds and are very frequently encountered structural motifs in organic synthesis. Herein we report an efficient synthesis of vinyl sulfides and vinyl sulfones via transition metal-free sodium iodide-mediated sulfenylation of alcohols and sulfinic acids with

A promoting effect of water was observed, leading to the dehydrative synthesis of allylic sulfones byTsuji–Trost reaction of non‐derivatized allylic alcohols with sulfinicacids. Mechanism studies suggested the formation of the eight‐membered ring complex from allylic alcohols, sulfinicacids, and water through hydrogen bonding may be crucial to the efficient activation of allylic alcohols.
A reciprocal-activation strategy for allylic sulfination with unactivated allylicalcohols was developed. In this reaction, the hydrogen bond interaction between allylicalcohols and sulfinic acids allowed for reciprocal activation, which enabled a dehydrative cross-coupling process to occur under mild reaction conditions. This reaction worked in an environmentally friendly manner, yielding water as

Dimethyldioxirae oxidizes aliphatic thiols to sulfinic acids in very good yield. Benzylic and aromatic thiols give a variety of other oxidation products using DMD.
