Abstract
Square-planar palladium complexes containing tridentate ligands with PXP (X = C, N, O, S, and As) donor sets have been prepared. For (Pd(POP-R)(CH3CN)2)(BF4)2 complexes (where POP-R is bis((diethylphosphine)ethyl)ether), bis((diphenylphosphino)ethyl)ether, or Bis((dicyclohexylphosphino)ethyl)ether), the POP-R ligands function as bidentate ligands. For all other complexes, the PXP ligands function as tridentate ligands. The dependence of the catalytic current on CO2 and acid concentrations is consistent with the formation of a hydroxycarbonyl intermediate which decomposes in the presence of acid to form hydrogen as the catalytic product.
