The synthesis of chiral square-planar PtII complexes using symmetrical and unsymmetrical bis(pinene)-fused 2,2′-bipyridine is described. The neutral diimine dichloro complexes show a strong deviation of the coordination sphere from planarity if the pinene groups are attached at the 5- and 6-positions of the pyridine rings. However, this distortion does not occur in parallel with the chiral configuration
描述了使用对称和不对称双 (蒎烯)-稠合 2,2'-联吡啶合成手性方形平面 PtII 复合物。如果蒎烯基团连接在吡啶环的 5 位和 6 位,则中性二亚胺二氯配合物显示出配位球与平面性的强烈偏差。然而,这种扭曲不会与二亚胺配体的手性构型同时发生。当使用手性二胺的外消旋混合物时,用二胺取代两个顺氯配体形成五元螯合环显示出很小的非对映选择性。此外,在连接中心是前手性的配体在配位时几乎没有选择性。
