Novel ketene dithioacetals have been synthesized by a one‐pot condensation reaction of active methylene compounds with CS 2 in the presence of alkyl acetylenecarboxylates. This reaction proceeds in a regioselective manner and provides products in good yields. The structures of the ketene dithioacetals were characterized by IR, 1 H‐ and 13 C‐NMR, and MS data, and elemental analyses.
