An efficient domino ruthenium‐catalyzed reverse water‐gas‐shift (RWGS)‐hydroformylation‐reduction reaction of olefins to alcohols is reported. Key to success is the use of specific bulky phosphite ligands and triruthenium dodecacarbonyl as the catalyst. Compared to the known ruthenium/chloride system, the new catalyst allows for a more efficient hydrohydroxymethylation of terminal and internal olefins
据报道,烯烃能有效地进行多米诺骨牌钌催化的反向水煤气变换(RWGS)加氢甲酰化还原反应。成功的关键是使用特定的大块亚磷酸酯配体和十二碳三钌作为催化剂。与已知的钌/氯化物体系相比,这种新型催化剂可以在较低温度下用二氧化碳更有效地对末端和内部烯烃进行羟羟甲基化。防止了底物的有害氢化。初步的机理研究揭示了活性催化剂的均相性质以及配体和添加剂在反应顺序的各个步骤中的影响。
