Facile stereoselective synthesis of an enantiomerically pure Δ-Ru-trisbipyridine type complex is accomplished by using a new chiral and conformationally rigid ligand, which completely predetermines the helical chirality of the metal, yielding exclusively 4-configuration in the present case. The ligand, abbreviated chiragen[6] is a bisbipyridine compound, where two pinene substituted bipyridine units
对映体纯 Δ-Ru-三联吡啶型复合物的简便立体选择性合成是通过使用新的手性和构象刚性配体完成的,该配体完全预先确定了金属的螺旋手性,在本例中仅产生 4-构型。配体,缩写为chiragen[6] 是一种双联吡啶化合物,其中两个蒎烯取代的联吡啶单元通过脂肪族C 6 链连接。复合物的两个剩余配位位点被 4,4'-二甲基联吡啶占据。已通过 X 射线晶体学确定了 Δ-[Ru(chiragen-[6])(4,4'-二甲基联吡啶)] (CF 3 SO 3 ) 2 复合物的结构
