Abstract

1, 2-Dichlorovinyl chalcogenides Ia–Ic of the general formula RXCCl= CHCl [R= Ar, Alk; X= S (a), Se (b), Te (c)] can be prepared by nucleophilic replacement of chlorine in trichloroethylene [1–5] or tetrachloroethane [6] by thiolate ion, addition of selenols [7, 8] to dichloroacetylene, phase-transfer reaction of benzeneselenol with trichloroethylene [9, 10], and addition of sulfenyl chlorides to chloroacetylene [5]. 1, 2-Dichlorovinyl selenides are ...
