Abstract

A phosphine containing a 10-vertex carborane anion substituent and its subsequent ligation to a Rh(I) carbonyl complex is reported. The complex is characterized by NMR spectroscopy and a single crystal X-ray diffraction study. In addition, the inductive effects of both 10 and 12 vertex C-functionalized closo-carborane anions are elucidated via I.R. analysis of the CO stretching frequencies of two Rh carbonyl complexes. Unlike C-functionalized neutral o-carborane the 10 and 12-vertex carborane anions are both strong electron donor substituents.

摘要

报道了一种含有10顶点碳硼烷阴离子取代基的膦及其与Rh(I)羰基配合物的后续连接。该配合物通过核磁共振光谱和单晶X射线衍射研究进行了表征。此外，通过对两种Rh羰基配合物的CO伸缩频率进行红外分析，阐明了10顶点和12顶点C-官能化的闭式碳硼烷阴离子的诱导效应。与C-官能化的中性邻碳硼烷不同，10顶点和12顶点的碳硼烷阴离子都是强电子供体取代基。
