Mixtures of the Z and E isomers of unsaturated organic selenides and 1,2-bis(organoseleno)mono(di)chloroethylenes were obtained by the addition of benzeneselenol and organic diselenides to the etherates of chloro- and dichloroacetylene
SELENYLATION OF cis- AND trans-1,2-DICHLOROETHYLENES AND VINYLIDENE CHLORIDE UNDER THE CONDITIONS OF PHASE-TRANSFER CATALYSIS

The reaction of PhSeH with cis- and trans-CHCl=CHCl, catalyzed by tributylbenzylammonium chloride, in 36percent sodium hydroxide solution with and without the presence of diethyl ether gives cis-PhSeCH=CHCl.The reaction also leads to the formation of trans-PhSeCH=CHCl and PhSeCCl=CH2 in small amounts, depending on the type of dichloroethylene and the presence of diethyl ether.Phenyl benzyl selenide is a side product for all the dichloroethylene isomers.The formation of the isomeric selenides was explained by the trans- and cis-addition of the selenol to the in situ generated chloroacetylene.

Alkyl and aryl selenide anions react with unactivated vinyl halides, in dipolar aprotic solvents, to give alkyl or aryl vinyl selenides in good yields.These reactions are stereospecific and occur with retention of configuration.
