Star-burst tetranuclear Ru(iii) complexes, Delta-(or Lambda-)[{Delta-(or Lambda-)-Ru(iii)(acac)(2)(taet)}(3)Ru(iii)] (acac = acetylacetonato; taet = tetraacetylethanato), were prepared and resolved into eight enantiomers on a column packed with an ion-exchange adduct of a clay and Delta-Ru(ii)(phen)(3) (phen = 1,10-phenanthroline), demonstrating that the dual chiralities of the central and peripheral regions were discriminated on the modified clay surface.
星爆四核钌(III)配合物,Delta-(或 Lambda-)[{Delta-(或 Lambda-)-钌(III)(乙酰丙酮)(2)(taet)}(3)钌(III)](acac = 乙酰丙酮根;taet = 四乙酰基乙醇酸根),被制备并在手性柱上分离为八种对映异构体,该手性柱填充有粘土与 Delta-钌(II)(phen)(3)(phen = 1,10-菲咯啉)的离子交换加合物,这表明中央和外围区域的双重手性在改性粘土表面上得到了区分。
