A visible‐light‐promoted oxathiacetalization of aldehydes and ketones with 2‐mercaptoethanol and 3‐mercaptopropan‐1‐ol in the presence of eosin Y as catalyst is described leading to the formation of 1,3‐oxathiolanes and 1,3‐oxathianes at ambient temperature and under metal‐free conditions. The solvent is playing vital role in the protection of carbonyl compounds with mercaptoalcohol.
