Sodium alkanethiolates or lithium methyl selenide react with styryl alkyl sulphides and selenides, in DMF at 100 deg C, to give the products of vinylic or aliphatic substitution.The two nucleophilic reagents are extremely selective.In the case of RSNa the

Heating to phenylacetylene with a mixture of thiophenol and dialkyl diselenide to 150-180°C yields previously unknown products of simultaneous addition to the phenylacetylene triple bond of alkylselenyl and phenthiyl groups, 2-alkylselenyl-1-phenyl-1-phenylthioethenes. The free-radical reaction mechanism is discussed.

Vinyl selenide anions, generated in DMF at 100 deg C, maintain the configuration of the vinyl methyl selenides from which they are produced by demethylation.This property has been used to effect an efficient three steps one pot stereospecific synthesis of vinyl alkyl selenides from unactivated vinyl halides.
