文摘

Photochemical reactions of diruthenium tetrahydride complexes containing cyclopentadienyls as auxiliary ligands with carbon dioxide were studied for the effective fixation and reduction of CO₂. Whereas the reactions of CpsRu(渭-H)₄RuCps (Cps = Cp*, C₅Me₅; Cp^Et, C₅Me₄Et; Cp^{鈥?/sup>, 1,2,4-C₅(tBu)₃H₂) with CO₂ did not proceed under dark and mild conditions, the photochemical reactions under UV (365 nm) irradiation smoothly proceeded to afford two types of products, (i) a 渭-formato complex and (ii) a 渭-carbonyl-渭-oxo complex, according to the width of the space for the reaction stretching between the two auxiliary cyclopentadienyl ligands.}
