• Kinetic and mechanistic analysis of a synthetic reversible CO₂/HCO₂⁻ electrocatalyst

  日期：——

  [Pt(depe)2](PF6)2 electrocatalyzes the reversible conversion between CO2 and HCO2− with high selectivity and low overpotential but low rates. A comprehensive kinetic analysis indicates the rate determining step for CO2 reduction is the reactivity of a Pt hydride intermediate to produce HCO2−. To accelerate catalysis, the use of cationic and hydrogen-bond donor additives are explored.

  [PT（DEPE）2 ]（PF 6）2 electrocatalyzes CO之间的可逆转换2和HCO 2 -以高选择性和低的超电压，但低速率。综合动力学分析指示用于CO的速率确定步骤2减少的PT氢化物中间体以产生HCO的反应性2 - 。为了加速催化，探索了使用阳离子和氢键供体添加剂。

  Treatments of the hydrido platinum(II) azide complex trans-PtH(N-3)(PEt3)(2) with organic isocyanides (CN-R) afforded trans-PtH[CN4(R)](PEt3)(2) (R = 2,6-Me2C6H3 (1a) or CH2SO2-C6H4-p-Me (2)) by cycloaddition of the isocyanides into the Pt-azido bond. Complex la readily isomerizes to cis-PtH[CN4(R)](PEt3)(2) (1b) at room temperature. The corresponding reactions with isothiocyanates (SCN-R) exclusively gave bis(tetrazole-thiolato) Pt(II) complexes, trans-PtS[CN4(R)](2)}(PEt3)(2) (R = 2,6-Me2C6H3 (3) or Ph (4)). Treatment of la with an equivalent of depe (1,2-bis(diethylphosphino)ethane) results in the formation of Pt(depe)(2) (5). (c) 2006 Elsevier B.V. All rights reserved.

  Reaction of 1,2-C6H4(SiMe2H)(SiH3) (8) with Pt(dmpe)(PEt3)(2) (dmpe = Me2PCH2CH2PMe2) or Pt(dmpe)(2) in 1:1 ratio at room temperature gave 1,2-C6H4(SiMe2)(SiH2)}Pt-II(dmpe) (11a) as a major product in solution. Complex 11a can easily dimerize to form [(dmpe)Pt-IV(H)- 1,2-C6H4(SiMe2)(mu-SiH}](2) (12a), and 11a and 12a are in equilibrium in solution. Although monomer 11a is a major species in solution, only dimer 12a crystallized out from toluene, THF, or DMF solution. Addition of excess dmpe to a toluene solution of 11a/12a trapped the Pt-II species as a pentacoordinated dimer [1,2-C6H4(SiMe2)(SiH2)}Pt-II(dmpe)](2)( mu-dmpe) (13). A similar reaction took place between 8 and Pt(depe)(PEt3)(2) (depe = Et2PCH2CH2PEt2) or Pt(depe)(2) to give 1,2-C6H4(SiMe2)(SiH2)Pt-II(depe) (11b) and [(depe)Pt-IV(H)1,2C(6)H(4)(SiMe2)(mu-SiH)}](2) (12b), and 11b, and 12b are in equilibrium in solution. Two equivalents of 8 reacted with Pt(dmpe)(PEt3)2 in toluene at room temperature to afford two isomeric 1,2-C6H4(SiMe2H)(SiH2)}1,2-C6H4(SiMe2)(SiH2)}(H)Pt-IV(dmpe) complexes 16 and 17 in 5:3 ratio among eight possible isomers. Heating the mixture of 16 and 17 at 100 degrees C in toluene resulted in slow intramolecular dehydrogenative cyclization to afford a mixture of isomeric 1,2-C6H4(SiMe2)(SiH2)}(2)Pt-IV(dmpe) 18 and 19. The structures of complexes 12a, 12b, 13, 17, 18, and 19 were unambiguously determined by single-crystal X-ray analysis.
