提出了一种新的反应，涉及含有半不稳定配体的超分子 Rh(I) 配合物中卤化物诱导的配体重排。三个类似的双和三半不稳定配体已被合成以构建双和三金属 Rh(I) 大环配合物。有意添加的卤化物源导致仅一种半不稳定配体沿着垂直于由半不稳定配体的芳基主链限定的平面的轴进行形式旋转。介绍了通过 X 射线晶体学确定的关键中间体和产品的 X 射线结构。
A novel reaction involving the halide-induced rearrangement of ligands within supramolecular Rh(I) complexes containing hemilabile ligands is presented. Three analogous bis- and trishemilabile ligands have been synthesized to construct bi- and trimetallic Rh(I) macrocyclic complexes. An intentionally added halide source results in the formal rotation of only one hemilabile ligand along the axis that is perpendicular to the plane defined by the aryl backbone of the hemilabile ligands. X-ray structures, as determined by X-ray crystallography, of key intermediates and products are presented.
