摘要：

The dicationic palladium(II) and platinum(II) complexes [(PNP)M(C2H4)]BF4)(2) (1a, M = Pt; 1b, M = Pd; PNP = 2,6-bis((diphenylphosphino)methyl)pyridine) and [(PPP)Pt(C2H4)](BF4)(2) (7; PPP = triphos) catalyze a cross-coupling reaction of ethylene with triand tetrasubstituted olefins, which can lead to both hydrovinylation and cyclopropanation products. The product ratio is strongly affected by the choice of the ligand and of the metal, the two limiting cases being la and 7, which selectively give the hydrovinylation and the cyclopropanation products, respectively.
