Two-dimensional double metal cyanide complexes: highly active catalysts for the homopolymerization of propylene oxide and copolymerization of propylene oxide and carbon dioxide

Abstract

The synthesis of two-dimensional double metal cyanide complexes of the formula Co(H2O)2[M(CN)4]·4H2O (M = Ni, Pd or Pt) and the X-ray crystal structure of Co(H2O)2[Pd(CN)4]·4H2O are presented. The anhydrous forms of these complexes were found to be effective catalyst precursors for the homopolymerization of propylene oxide as well as the random copolymerization of propylene oxide and carbon dioxide to produce poly(propylene oxide-co-propylene carbonate) with no propylene carbonate byproduct. A detailed copolymer microstructure is proposed.
