Characterisation of hydridopalladium complexes
Abstract
The hydride complexes trans-[PdH(X)(PPh3)2](X = Cl or Br) have been prepared in good yield by hydrogenolysis of trans-[PdX(COPh)(PPh3)2] or trans-[PdXPh(PPh3)2]. They have been fully characterised by NMR and IR spectroscopic measurements and shown to have the trans configuration. The mechanism of the hydrogenolysis reaction and the role of these hydride species in catalytic reactions are discussed.
