具有氨基酸部分的手性组织的醌二亚胺衍生物被证明与2摩尔当量反应。的Pd（0Ac）2，导致形成手性同双金属钯（II）配合物。手性共轭配合物的晶体结构显示醌二亚胺氮与钯中心的配位和π共轭骨架的手性螺旋桨扭曲构象。的镜像关系的CD信号周围的醌二亚胺部分在乙腈中观察betweenl-和d-衍生物，表明即使在溶液中的手性组织结构的保存。
The chirality-organized quinonediimine derivatives bearing amino acid moieties were demonstrated to react with 2 molar equiv. of Pd(OAc)2, resulting in the formation of the chiral homobimetallic palladium(II) complexes. The crystal structures of the chiral conjugated complexes revealed the coordination of the quinonediimine nitrogen to a palladium center and a chiral propeller twist conformation of the π-conjugated backbone. The mirror image relationship of the CD signals around the quinonediimine moieties in acetonitrile was observed betweenl- andd-derivatives, indicating the preservation of the chirality-organized structures even in a solution.
