A simple and efficient chemoselectivethioacetalization of carbonylcompounds has been achieved using Ce(OTf)3 (10 mol-%) as a catalystunder solvent-free conditions. Advantages of the methodology include very short reaction times, excellent yields, the catalytic use of a water tolerant Lewis acid, and simple recovery and reuse of the catalyst.
