Mediated electrochemical reduction of CO/sub 2/. Preparation and comparison of an isoelectronic series of complexes
The preparation and characterization of complexes of the type (M(triphos)L)(BF/sub 4/)/sub 2/ are described (for M = Ni, L is P(OMe)/sub 3/ and PEt/sub 3/; for M = Pd, L is CH/sub 3/CN, P(OMe)/sub 3/, PEt/sub 3/, P(CH/sub 2/OH)/sub 3/, and PPh/sub 3/; for M = Pt, L is PEt/sub 3/; triphos is PhP(CH/sub 2/CH/sub 2/PPh/sub 2/)/sub 2/). On the basis of cyclic voltammetry and bulk electrolysis experiments, the Pd complexes are shown to catalyze the electrochemical reduction of CO/sub 2/ to CO in acidic acetonitrile solutions. The analogous Ni and Pt complexes are not catalysts for CO/sub 2/ reduction under the same conditions. Kinetic studies have been carried out on (Pd(triphos)(PEt/sub 3/))(BF/sub 4/)/sub 2/ and a mechanism for the reduction of CO/sub 2/ is proposed.
