Coordination chemistry of 2,2′-bipyridine bearing an ortho-substituted phenyl group at the 6-position, i.e., 6-(o-X-phenyl)-2,2′-bipyridine (MeO-L: X = OMe; Me2N-L: X = NMe2) with [Ru(ttpy)Cl3] (ttpy = 4′-(4-tolyl)-2,2′;6′,2″-terpyridine) was investigated. The reaction of MeO-L and [Ru(ttpy)Cl3] in the presence of N-methylmorpholine afforded demethylated, O-coordinated complex [Ru(O-L)(ttpy)]+ (O-L: X = O)
在6-位带有邻位取代苯基的2,2'-联吡啶的配位化学,即6-(邻-X-苯基)-2,2'-联吡啶(MeO-L:X = OMe; Me研究了具有[Ru(ttpy)Cl 3 ](ttpy = 4′-(4-甲苯基)-2,2′; 6′,2″-吡啶基)的2 N-L:X = NMe 2。在N-甲基吗啉的存在下MeO-L与[Ru(ttpy)Cl 3 ]的反应提供了脱甲基的O配位络合物[Ru(OL)(ttpy)] +(OL:X = O)以及环金属化的C配位络合物[Ru(MeO-L)(ttpy)] +。另一方面,我2的反应在N-甲基吗啉存在下,NL和[Ru(ttpy)Cl 3 ]仅提供N配位的络合物[Ru(Me 2 N-L)(ttpy)] 2+。通过DFT计算补充了晶体结构,光谱学和氧化还原特性。RuN的光谱和氧化还原特性与[Ru(ttpy)Cl 3]。另一方面,RuC和RuO的性质彼此相似,但与RuN的性质
