The nucleophilic substitution of compounds ACFCFCl (ARO, RS) proceeds by addition-elimination. The observed regioselectivity depends upon the nature of A. The stereospecificity is explained by steric hindrance in the transition state of the elimination step. Butyllithium also promotes a lithium—chlorine exchange.

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'.
