The synthesis of a ruthenium complex bearing a PN-chelating ligand is described. The complex, in the presence of KOH, enabled the synthesis of ketones from secondary alcohols in the absence of a hydrogen acceptor in aqueous medium. This synthetic protocol, which uses water as the medium, is green and has a high atom economy as it avoids the use of an acceptor and produces hydrogen as the sole byproduct
描述了带有 PN 螯合配体的钌配合物的合成。在 KOH 存在下,该复合物能够在水性介质中不存在氢受体的情况下从仲醇合成酮。这种使用水作为介质的合成方案是绿色的,并且具有高原子经济性,因为它避免了使用受体并产生氢作为唯一的副产品。机理研究表明,催化循环涉及磷化氢解离途径。
