A simple and modular protocol for the olefination of aldehydes with thiols as reaction partners is reported. Olefins with both aromatic and aliphatic substituents were synthesized in high yields and good selectivity via unsymmetric bissulfone intermediates. The E/Z-selectivity could be switched under kinetic control through the choice of solvent. The use of simple, transition metal-free reaction conditions
Direct thioetherification from a variety of aromatic carboxylic acids and thiols using a reducing system combined with InBr3 and 1,1,3,3-teramethyldisiloxane (TMDS) in a one-pot procedure is demonstrated. It was also found that a system combined with InI3 and TMDS underwent thioetherification of aliphatic carboxylic acids with thiols.
