1,2-Dichloroethylene reacts with hydrogen sulfide in the gas phase at 420 - 520 deg C in an empty quartz tube, forming bis(β-chlorovinyl)sulfide (geometric isomers), 2- and 3-chlorothiophene, 2,4-dichlorothiophene, 2- and 3-thienyl β-chlorovinyl sulfides (cis and trans isomers), cis-4-chloro-2-thienyl β-chlorovinyl sulfide, and thieno- and thienothiophenes.The yields of these compounds depend on the reaction conditions (temperature, contact time, ratio of initial reagents).At 480 deg C in an excess of 1,2-dichloroethylene the yield of the mixture of2- and 3-chlorothiophene amounts to 25percent (ratio 3 : 1).
