Abstract

A mild and efficient neutral aqueous method for selective cleavage ofacetals and ketals to the corresponding carbonyl compounds has been established by using LiCl in H2O-DMSO at elevated temperature. While aryl and alpha,beta-unsaturated ketals and acetals underwent smooth cleavage, diaryl, non-aryl and isolated ketals and acetals remained unaffected under the reaction conditions.
