Abstract
A Lewis acid-surfactant-combined copper bis(dodecyl sulfate) [Cu(DS)2] catalyst served as an efficient and reusable catalyst for the thioacetalization and transthioacetalization of carbonyl compounds and O,O-acetals in water at room temperature. This procedure offers high chemoselectivity, ease of operation and purification without any organic solvent, and high yields.
