Bnezyl methyl sulphide is readily cyclopalladated by palladium acetate.Compared with the chloride bridged-derivative, the cationic cyclopalladated compounds are more reactive towards the insertion of alkyne into their Pd-C ? bonds, which leads in some cases to cationic organic heterocycles containing either a six- or an eight-membered ring, arising from insertion of one or two alkyne molecules, the C-S bond being formed via reductive elimination of palladium(0).
