New nitrogen- and sulfur-containing compounds, bicyclic and monocyclic, were prepared and evaluated as ligands in the transfer hydrogenation of acetophenone. Utilising [Ir(COD)Cl]2 as metal precursor the best result, 80% ee, was obtained using a bicyclic sulfoxide ligand.
新型含氮和含硫单环及双环化合物被制备并作为配体用于乙酰苯的氢转移反应中评估。使用[Ir(COD)Cl]2作为金属前驱体,通过一种双环亚砜配体获得了最佳结果,即80%的ee(对映体过量)。
