Abstract
The synthesis and characterization of [M(Bu3P+etpE)Br](BF4)2 (where M = Ni or Pd and Bu3P+etpE = [(Bu3PCH2CH2)P(CH2CH 2PEt2)2]+) and [M(etpPBu3 +)Br]Br(BF4)4 (where M = Ni or Pd and etpPBu3 + = {PhP[CH2CH2P(CH2CH2PBu 3)2]2}4+) are described. The structure of [Ni(etpPBu3 +)Br]Br(BF4)4 has been determined by X-ray diffraction. Treatment of [Pd-(Bu3P+etpE)Br](BF4)2 with AgBF4 in acetonitrile produced [Pd(Bu3P+etpE)(CH3CN)](BF4) 3. The latter compound has also been characterized by single-crystal X-ray diffraction methods. Electrochemical studies indicate that this compound and its closely related methyl analog, [Pd(Me3P+etpE)(CH3CN)](BF4) 3, are catalysts for the electrochemical reduction of CO2 to CO in acidic dimethylformamide solutions. Kinetic and mechanistic studies of this catalytic reaction are reported.
