| Abstract: | Thioacetalization reaction of 2-(1,3-dialkylthio)-2-ylidene-3-oxo-butanamide 1 as substitution reagent of ethylthiol、ethanedithiol and benzylthiol catalyzed by benzoyl chloride and using ethanol as solvent was carried out successfully.The results showed that 2-(1,3-dialkylthio)-2-ylidene-3-oxo-butanamide could be used as thiol equivalent in the conversion of aromatic aldehydes into the corresponding dithioacetals with high yields.The structures of various product compounds were characterized and the reaction mechanism of thioacetalization was proposed. |
