Synthesis of heterodinuclear hydride complexes by oxidative addition of a transition-metal hydride to Pt(0) and Pd(0) complexes

Heterodinuclear hydridoplatinum and -palladium complexes, L′2HPt(or Pd)MLn were synthesized by the oxidative addition of corresponding mononuclear hydride complex with zero-valent platinum and palladium complexes. Facile exchanging process between H and M in (dppe)HPt(or Pd)MLnis observed. Reversible hydride migration from Pt(or Pd) to M was enhanced by electron deficient alkenes.117
