A mild and environmentally friendly method to synthesize half-sandwich ruthenium complexes through the Wittig reaction between an aldehyde-tagged half-sandwich ruthenium complex and phosphorus ylide mechanochemically is reported herein. The mechanochemical synthesis of valuable half-sandwich ruthenium complexes resulted in a fast reaction, good yield with simple workup, and the avoidance of harsh reaction
本文报道了通过醛标记的半三明治钌络合物与磷内酯的机械化学反应通过Wittig反应合成半三明治钌络合物的温和且环保的方法。机械化学合成有价值的半三明治钌络合物可实现快速反应,良好收率和简单后处理,并且避免了苛刻的反应条件和有机溶剂。以2-丙醇为氢源和溶剂,合成的半三明治钌配合物对酮的加氢反应具有很高的催化活性。运用密度泛函理论提出了转移加氢过程的机理。建模表明不稳定的p的重要性-cymene配体可调节催化剂的反应性。
