The salts of 1,1-vinylidenedithiols react with bromo(methoxy-carbonyl)acetylene in alcohol buffer solutions with the formation of 2-alkylidene-4-methoxycarbonyl-1,3-dithioles.The structure of (E)-2-N-phenylsulfonylimino-4-methoxycarbonyl-1,3-dithiole, formed in the reaction of the N-phenylsulfonyldithiocarbonimidate salt with this halogenoacetylene, was proved by x-ray crystallographic analysis.
