We report the first examples of ruthenium complexes cis-[(N4)RuIIICl2]+ and cis-[(N4)RuII(OH2)2]2+ supported by chiral tetradentate amine ligands (N4), together with a high-valent cis-dioxo complex cis-[(N4)RuVI(O)2]2+ supported by the chiral N4 ligand mcp (mcp = N,N′-dimethyl-N,N′-bis(pyridin-2-ylmethyl)cyclohexane-1,2-diamine). The X-ray crystal structures of cis-[(mcp)RuIIICl2](ClO4) (1a), cis-
我们报告了由手性四齿胺配体 (N 4 ) 支持的钌配合物cis -[(N 4 )Ru III Cl 2 ] +和cis -[(N 4 )Ru II (OH 2 ) 2 ] 2+的第一个例子,与手性N 4配体mcp ( mcp = N , N ' -二甲基-N _, N'-双(吡啶-2-基甲基)环己烷-1,2-二胺)。cis -[(mcp)Ru III Cl 2 ](ClO 4 ) ( 1a )、cis -[(Me 2 mcp)Ru III Cl 2 ]ClO 4 ( 2a ) 和cis -[(pdp )的 X 射线晶体结构)Ru III Cl 2 ](ClO 4 ) ( 3a ) (Me 2 mcp = N , N '-二甲基-N , N'-双((6-甲基吡啶-2-基)甲基)环己烷-1,2-二胺, pdp = 1,1'-双(吡啶-2-基甲基)-2,2'-联吡咯烷))配体以顺式-α构型与钌中心配位。在水溶液中,观察到cis
