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.

3-mercapto-3-methoxy-1-phenyl-2-propen-1-one was synthesized by the reaction of 3-bromo-1-phenyl-2-propyn-1-one with thiobenzamide in alcohol without a catalyst or in the presence of catalytic amounts of triethylamine.In the presence of an equimolar amount of potassium hydroxide 2,4-bis(benzoylmethylene)-1,3-dithietane was obtained with a good yield.
