The effect of substituents and reaction conditions (solvents) on the dichotomy in the reaction of 1,1-ethenedithiolates with activated halogenoacetylenes and β,β-dihalogenovinyl derivatives was investigated.The reaction results in the formation of 2-alkylidene-1,3-dithioles and/or unsymmetrical 2,4-dialkylidene-1,3-dithietanes (desaurins).The second direction of the reaction could only be realized in the case of 1-acyl-2-halogenoacetylenes (1-benzoyl-2-bromoacetylene) and β,β-dichlorovinyl ketones in sufficiently polar solvents.

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.
