A simple and efficient catalytic method for dithioacetalization of various carbonyl compounds (saturated and α,β-unsaturated aliphatic, aromatic, heteroaromatic and hindered) with ethanethiol and 1,3-propanedithiol using H-Y and H-mordenite (H-M) zeolites is described. The reaction affords moderate to excellent yields of the corresponding products.
