Reactions of tris(triphenylphosphine)platinum(o) and tetrakis(triphenylphosphine)palladium(o) with oxygen and carbon dioxide

Abstract

The oxygen compounds (Ph₃P)₂MO₂(M = Pd or Pt) have been prepared by the action of oxygen on (Ph₃P)₄Pd and (Ph₃P)₃Pt respectively. In presence of carbon dioxide the corresponding carbonato-complexes, (Ph₃P)₂MCO₃, which may be isolated also as solvates, are obtained. The latter are characterised by spectroscopic and chemical techniques and some of their reactions described.
