Abstract We have demonstrated a facile and direct synthesis of sulfide derivatives using acetals and ketals, derived from aromatic/conjugated aldehydes and aromatic ketones, with disulfides and the InBr 3 –Et 3 SiH reducing system. We also succeeded in developing an unprecedented one‐pot preparation of an aliphatic sulfide from a disulfide and an aliphatic acetal. (© Wiley‐VCH Verlag GmbH & Co.
