only discuss symmetrical dithioacetals. Examples of mixed dithioacetals are scarce and no general method for the selective synthesis of these compounds exists. Herein, a synthetically simple general one‐step protocol was developed for the synthesis of a broad range of unsymmetrical dithioacetals consisting of one aromatic and one aliphatic thiol moiety from the corresponding aldehyde/thiol mixture.

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
