A mild and efficient procedure for the preparation of dimethyl and diallyl acetals of aromatic aldehydes mediated by cerium(IV) ammonium nitrate

摘要

The reaction of aromatic aldehydes with cerium(IV) ammonium nitrate (CAN) in alcohols to afford the corresponding acetals is described.In the context of our interest in the area of CAN mediated carbon-carbon bond forming reactions,we were intrigued by the possibility of CAN mediated oxidative addition of aldehydes to alkenes.
