  Palladium-catalyzed cross-coupling reactions between organic tellurides and alkenes

  摘要：

  Diaryl tellurides, alkenyl aryl tellurides and dialkenyl tellurides react efficiently with various alkenes in methanol in the presence of a catalytic amount of PdCl2 together with AgOAc and Et(3)N to give the corresponding aryl- and alkenyl-substituted alkenes with moderate to quantitative yields. Both monomeric and dimeric palladium complexes, (Ph(2)Te)(2)PdCl2 and [(Ph(2)Te)PdCl2](2) respectively, react readily with alkenes to give a high yield of phenyl-substituted alkenes. The key step of this coupling reaction is proposed to be the migration of an organic moiety from Te to Pd (transmetallation) in organic telluride-PdCl2 complexes to afford organopalladium species.
