Alkenylmetals of Zn or Al containing α-alkoxy, α-alkylthio, or α-trialkylsilyl substituents react readily with aryl or alkenyl halides in the presence of a Pd catalyst to produce arylated alkenes or conjugated dienes, respectively, the stereospecificity of the reactions for the synthesis of 1, 3, 4, and 5 being > or = 98percent.

When heated with phenylacetylene in aqueous THF, potassium ethyltrithiocarbonate forms 1-phenyl-1-ethylthioethene in addition to cis-1-phenyl-2-ethylthioethene.The reaction takes place in DMSO, dioxane, benzene, and ethanol.It was established that cis-1-phenyl-2-ethylthioethene is formed exclusively in DMSO and 1-phenyl-1-ethylthioethene is formed in benzene.The reaction of potassium trithiocarbonate with ethylene in DMSO leads to divinyl sulfide.
