Abstract

The coordinated ethylene molecule in the dicationic complex [(PNP) Pt (CH2 CH2)](BF4) 2 (PNP= 2, 6-bis (diphenylphosphinomethyl) pyridine) undergoes nucleophilic attack by free internal alkenes, giving the isolable complexes [(PNP) Pt (CH2 CHCH (Me) CMeRR'](BF4) 2 (R, R'= H, Me) and providing a new effective pathway for a chemo-and regio-selective catalytic hydrovinylation reaction.
