A novel, mononuclear Ti(IV) amine triphenolate complex obtained by reaction of Ti(OiPr)(4) with tris(2-hydroxy-3-phenylbenzyl)amine bearing phenyl ortho-substituents affords quantitatively and spontaneously the corresponding heterochiral micro-oxo dinuclear compound whereas an analogous chiral, enantiopure complex maintains its mononuclear structure even in the presence of an excess of water.
通过Ti(OiPr)(4)与带有三(2-羟基-3-苯基苄基)胺的苯基邻位取代基反应获得的新型单核Ti(IV)胺三酚复合物可定量并自发地提供相应的杂手性微氧代双核化合物,而类似的手性对映纯络合物即使在过量水的存在下也能保持其单核结构。
