Various carbonyl compounds can be easily and rapidly converted to the corresponding 1,3-oxathiolanes in the presence of a catalytic amount of scandium(III) triflate in CH2Cl2. The catalyst can be recovered. A chemoselective oxathioacetalization of aldehydes in the presence of ketones can be achieved.
