摘　　要：合成了一种基于吡啶骨架含有苯并咪唑和手性咪唑啉基团的三齿NNN配体及其二价钌(Ⅱ)配合物,通过核磁共振波谱学和X射线单晶晶体结构测定确认了钌(Ⅱ)配合物的分子结构.这些配合物在室温下催化酮的氢转移反应,表现出了优异的催化活性,收率和ee值最高分别可达99%和97%.Ru（Ⅱ） complexes bearing pyridyl‐based benzimidazolyl‐imidazolinyl tridentate NNN ligands were synthesized and structurally characterized. Their molecular structure was confirmed by X‐ray crystallography. These complexes demonstrated good to excellent catalytic activity in the asymmetric transfer hydrogenation of ketones at room temperature, achieving up to 99% yields and 97% ee values.
