FeCl3 Promoted aqueous α-C-H sulfonylmethylation of α-oxo ketene dithioacetals with aryl sulfonylmethyl isocyanides are developed, and the green synthesis of α-sulfone methyl ketene dithioacetals are achieved in good yields. The reaction features high atom economy and yields, broad substrate scope, enabling gram-scale reaction and avoiding the use of toxic and harmed organic solvents, which conforms to the concept of green chemistry and is of great significance for environmental protection.

Key words: Aqueous reaction, ketene dithioacetals, ferric chloride, p-tolylsulfonymethyl isocyanide, sulfonylmethylation
