The reaction of ClCCCl, PhCCCl and PhSCCCl with a variety of tertiaryenolates leads in 43–90% yields to α-chloroethynyl, α-phenylethynyl and α-thiophenylethynyl derivatives. The −CCCl group is smoothly converted to −CCH using copper powder in HOAc/THF, or is directly reduced (H2/Lindlar catalyst) to the −CHCH2 group, thus providing facile access to many α-ethynyl and α-vinyl ketones and esters

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'.
