Exceptionally active ruthenium(II) complexes without an ancillary NH functionality, but bearing a (chiral) unsymmetrical pyridyl‐benzimidazolyl‐based NNN ligand, exhibited very high catalytic activity in the (asymmetric) transfer hydrogenation ((A)TH) of ketones. The corresponding RuH complex, which is presumably the catalytically active species, was successfully isolated and structurally characterized
异常活性钌(II)配合物而没有辅助Ñ H官能团是否,但轴承(手性)不对称吡啶基苯并咪唑为基础的NNN配体,在((A)TH)酮的(非对称)转移氢化表现出非常高的催化活性。相应的RuH配合物(可能是催化活性物质)已成功分离并通过X射线晶体学对其结构进行了表征。
