  Key Process of the Photocatalytic Reduction of CO₂ Using [Re(4,4‘-X₂-bipyridine)(CO)₃PR₃]⁺ (X = CH₃, H, CF₃; PR₃ = Phosphorus Ligands):  Dark Reaction of the One-Electron-Reduced Complexes with CO₂

  摘要：

  Reduction of CO2 to CO was efficiently photocatalyzed by [Re(4,4'-X(2)bpy)(CO)(3)PR3](+) (X = H, Me; PR3 = P(OEt)(3), P(O-i-Pr)(3)) in quantum yields of 0.16-0.20. Complexes with CF3 as X or trialkylphosphine as PR3 have much lower photocatalytic ability. One-electron-reduced species of the complexes, which were produced by the photoinduced electron-transfer reaction with triethanolamine, reacted with CO2 in the dark with rate constants of 3.5 x 10(-4)-1.9 x 10(-2) M-1 s(-1). The faster the rate of this process, the higher the quantum yield of CO formation. The calculated amount of CO formation, based on the assumption that the process gives CO quantitatively, was similar to the actually observed amount under various conditions. This is consistent with the thermal process being one of the rate-limiting steps in the photocatalyzed reduction of CO2 by the rhenium complexes.

  摘要：

  摘要 报道了一系列 Re(二亚胺)(CO)2(L)Cl（其中 L = P(OEt)3，PMe3）类型的化合物的合成和表征。非光化学配体取代 (non-PLS) 利用磷配体的转稳定作用来促进羰基取代。非 PLS 途径导致单一异构体产品的高产率 (> 60%)，与类似 PLS 途径的低产率、混合异构体产品相比具有优势。羰基被膦/亚磷酸酯配体取代，将吸收进一步转移到可见光区域，而不会降低摩尔吸收率。所提出的合成为相关的光敏中性铼/锰羰基卤化物化合物提供了一种通用的简便配体取代途径。
