Carbonyl compounds have been successfully converted into their corresponding oxathiolane, dithiolane, and dithiane derivatives with 2-mercaptoethanol, 1,2-ethanedithiol, and 1,3-propanedithiol using a catalytic amount of yttrium triflate. In addition, by using this catalyst, highly chemoselective protection of aldehydes has been achieved.
