Abstract

Carbonyl compounds have been successfully converted into their corresponding dithiolanes and dithianes derivatives with 1, 2-ethanedithiol and 1, 3-propanedithiol in excellent yield at room temperature and short reaction times using a catalytic amount of magnesium hydrogensulfate. The synthetic simple procedures reported in this paper constitute an exceptionally mild procedure for carbonyl protection in ambient conditions.
