An active and selective dual catalytic system to promote domino hydroformylation–reduction reactions is described. Apart from terminal, di‐ and trisubstituted olefins, for the first time the less active internal C−C double bond of tetrasubstituted alkenes can also be utilized. As an example, 2,3‐dimethylbut‐2‐ene is converted into the corresponding n‐alcohol with high yield (90 %) as well as regio‐ and chemoselectivity (>97 %). Key for this development is the use of a combination of Rh complexes with bulky monophosphite ligands and the Ru‐based Shvo's complex. A variety of aromatic and aliphatic alkenes can be directly used to obtain mainly linear alcohols.

双Rh-Ru催化剂将烯烃还原加氢甲酰化为醇

描述了一种促进多米诺加氢甲酰化-还原反应的主动选择性双催化体系。除了末端取代的二，三取代烯烃外，还第一次可以使用四取代烯烃的活性较低的内部CC双键。例如，将2,3-二甲基丁-2-烯转化为相应的正丙醇，产率高（90％），区域和化学选择性（> 97％）。该开发的关键是将Rh配合物与庞大的单亚磷酸酯配体和Ru基Shvo配合物结合使用。可以直接使用多种芳族和脂族烯烃来获得主要为线性的醇。
