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.

A recyclable biphasic system for stereoselective and easily handled hydrochalcogenations

Vinyl selenides and vinyl sulfides were prepared by hydrochalcogenation of alkynes with selenols and thiols generated in situ by the reduction of the corresponding diselenides and disulfides with elemental zinc in a biphasic acidic medium. The yields, ste

Rhodium-Catalyzed Regio- and Stereoselective 1-Seleno-2-thiolation of 1-Alkynes

Rhodium complex RhH(PPh3)4 and 1,1′-bis(diphenylphosphino)ferrocene catalyze the regio- and stereoselective additions of diaryl disulfides and diaryl diselenides to 1-alkynes giving (Z)-1-arylseleno-2-arylthio-1-alkenes. The catalyst promotes the addition reaction of dibutyl disulfide and dibutyl diselenide to 1-octyne with a similar selectivity giving (Z)-1-butylseleno-2-butylthio-1-octene but with a lower catalytic activity. The same product is obtained with a higher yield, when excess dibutyl disulfide is used against dibutyl diselenide in the presence of RhH(PPh3)4 and 1,4-diphenylphosphinobutane.
