and steric effects of the substituents on ligands and substrates.Graphical Abstract A new series of C2-symmetric bis(sulfonyl) tetraaza ligands was synthesized from (1S,2S)-1,2-diarylethylenediamine analogues and tested in the asymmetric transfer hydrogenation of aromatic ketones by complexing with [Ru(η6-p-cymene)Cl2]2 employing formate sodium as hydrogen source in neat water. A moderate to excellent
摘要在本报告中,由 (1S,2S)-1,2-二芳基乙二胺类似物合成了一系列新的 C2 对称双(磺酰基)四氮杂配体,并通过与 [Ru (η6-p-cymene)Cl2]2 使用甲酸钠作为纯水中的氢源。通过取代基对配体和底物的不同电子和空间效应,获得了中等至优异的转化率 (~99.8%) 和总体令人满意的对映选择性 (~92.8%)。 图形摘要 一系列新的 C2 对称双(磺酰基)四氮杂配体由 (1S,2S)-1,2-二芳基乙二胺类似物合成,并通过与 [Ru(η6-p-cymene)Cl2]2 配合使用甲酸钠作为纯水中的氢源,在芳香酮的不对称转移氢化中进行了测试。
