KHSO4: a catalyst for the chemo-selective preparation of 1,1-diacetates from aldehydes under solvent-free conditions

Abstract

A simple, mild, effective and green method to form acylals from aliphatic and aromatic aldehydes in good to excellent yields in the presence of potassium hydrogen sulfate, KHSO4, as catalyst under solvent-free conditions is described. Ketones are not affected under the reaction conditions.
