Polycarbonates (PCs) were prepared by oxidative carbonylation of bisphenol A and carbon monoxide, using a Pd‐polybipylidyl complex, Pd‐polyvinylpyridine complex, smectite‐supported Pd complex, or hydrotalcite‐supported Pd complex as a heterogeneous Pd catalyst to separate the PC solution and the Pd catalyst after the reaction. Propylene carbonate was used as a halogen‐free solvent. When Co(OAc) 2 ·4H 2 O was used as the inorgano‐redox catalyst, all of the Pd compounds gave a good PC yield with the recycling potential of the catalyst. © 2008 Wiley Periodicals, Inc.
