Synthesis of unsaturated organochalcogen compounds proceeding from dichloroethenes and organyl dichalcogenides

Reaction of 1,1- and 1,2-dichloroethenes with Ph2S2, Ph2Se2, Bn2S2, and i-Pr2S2 in a system hydrazine hydrate–KOH proceeds as a sequence of successive transformations: dehydrochlorination of initial dichloroethenes to form chloroacetylene, chlorine substitution for the chalcogen-containing nucleophile (ethynylchalcogenides formation), and the addition of the nucleophilic reagent to the triple bond affording 1,2- dichalcogenylethenes. In reactions with PhS– and PhSe? nucleophiles due to the high rate of all stages 1,2-bis (phenylchalcogenyl)ethenes are obtained having mainly the Z-configuration. In reactions with BnS? and i-PrS? in the IR, NMR and chromato-mass spectra intermediate ethynylchalcogenides were identified, and the final products consisted of a mixture with the prevalence of the Z-isomer.

The role of palladium catalyst and base in stereoselective transformations of (E)-2-chlorovinylsulfides

Stereoselective transformations of 2-chlorovinylsulfides in the presence of soluble (t-BuOK) or insoluble (solid KOH or Cs2CO 3/18-crown-6) base and palladium catalyst (dppb)Pd(OAc)2 have been studied. Depending on the sub
