(Alkylthio)chloroacetylenes 1 react with thiosemicarbazones 2 at room temperature in a medium of aliphatic ketone to form hydrochlorides of 2-alkanone-N-[4-(organylthio)-1,3-thiazol-2-yl]hydrazones 3 in yields of up to 65%.

(Alkylthio)chloroacetylenes are readily hydrochlorinated with hydrogen chloride in dioxane to form a mixture of (E)- and (Z)-1-(alkylthio)-1,2-dichloroethenes, as well as 1-(alkylthio)-1,1,2-trichloroethanes.

The reaction of organylthiochloroacetylenes RSC-alpha = C-beta-Cl with selenols in a DMSO solution containing KOH leads to organylthio(organylseleno)acetylenes RSC = CSeR'. When the reaction of organylthiochloroacetylenes with selenols was carried out in diethyl ether, the previously unknown 1-organylthio-2-organylseleno-2-chloroethenes RSCH = CClSeR' were obtained in the form of Z- and E-isomers. The hydrochlorination of organylthio(organylseleno)acetylenes results in Z- and E-1-organylthio-2-organylseleno-1-chloroethenes RSCCl = CHSeR'.
