Alkoxo complexes, M(OR)Ln and MH(OR)Ln (M=Co, Rh, Ru; L=PPh3; R=CH(CF3)2, CHPh(CF3)), have beeen prepared by insertion of fluoroketones into M–H bonds in CoH(N2)L3, RhHL4, and RuH2L4. Hydrogenolysis of the Ru- and Rh-alkoxo complexes with H2 or ethanol liberates corresponding fluoroalcohols in good yields. Catalytic activity in hydrogenation of ketones is correlated with the ease of hydrogenolysis
烷氧基配合物 M(OR)Ln 和
MH(OR)Ln(M=Co、Rh、Ru;L=PPh3;R=CH(
CF3)2、CHPh( ))已通过将
氟酮插入 M 中制备CoH(N2)L3、RhHL4 和 RuH2L4 中的 –H 键。Ru-和Rh-烷氧基配合物与H 2 或
乙醇的氢解以良好的产率释放相应的
氟代醇。酮氢化中的催化活性与烷氧基配合物的氢解容易程度相关。
