Hu, Bowen published the artcileHalf-sandwich ruthenium (II) complexes with bidentate NN ligands: active catalysts for synthesis of quinolines and pyrroles by acceptorless dehydrogenative cyclization, Quality Control of 96-20-8, the publication is Youji Huaxue (2020), 40(1), 53-60, database is CAplus.
Four (η6-p-cymene)Ru(II) complexes with bidentate NN ligands, (η6-p-cymene)Ru(C5H4N-C5H3N-OH), (η6-p-cymene)Ru(C5H4N-CH2-C5H4N), (η6-p-cymene)Ru(C5H4N-CH2-C5H3N-OH) and (η6-p-cymene)Ru(C5H4N-CH2-C5H3N-OCH3) were prepared These complexes were all characterized by 1H NMR, 13C NMR and elemental anal., and (η6-p-cymene)Ru(C5H4N-CH2-C5H4N) was further determined by single crystal crystallog. Complexes were treated as catalysts for cyclizations of amino alcs. with ketones, and (η6-p-cymene)Ru(C5H4N-CH2-C5H3N-OH) exhibited the highest activity. The cyclization reactions proceeded in toluene with 0.5 mol% catalyst loading, and a series of quinolines and pyrroles were synthesized.
