A copper-catalyzed vicinal chloro-thiolation of alkynes with inexpensive and diversified sulfonyl chlorides RSO2Cl (R = aryl, alkyl) has been developed. This practical and scalable reaction could be used for the construction of a number of unexplored bioactive chlorothiolated alkenes. Internal alkynes could also undergo the chloro-thiolation to provide tetrasubstituted alkynes. Preliminary mechanistic investigations revealed a plausible radical process involving a sulfur-centered radical intermediate via copper-mediated homolysis of the S-Cl bond.

Both the stereo- and regio-chemical reactivity of the phthalimidesulfenyl chloride 1 towards symmetrical and terminal acetylenes and the reactivity of the adducts 3 and 5 with various nucleophiles has been investigated.Nucleophilic substitution of the phthalimide residue was achieved with MeLi, PhLi, ButLi, (Me3Si)2NNa and Me3SiSMe.The synthesis of β-chlorovinyl tributylstannyl sulfides 14 is also described.The synthetic potential of the new sulfur compounds is discussed.

(E)- and (Z)-1,2-bis(phenylsulphonyl)stilbenes (12 and 9) have been synthesized starting from (E)- and (Z)-1-phenylthiostilbenes (1 and 3).The geometrical configurations of these compounds have been established through stereospecific synthesis.
