Phosphacarborane Chemistry. Triphosphacarboranes nido 4-Ch_3-7, 8, 9, 10,-P_3CB_7H_7 and nido-4-CH_3-11-Cl-7, 8, 9, 10-P_3CB_7H_6, Analogues of 7, 8, 9, 10-C_4B_7H_(11) and the First Examples of Boron Culsters Containing Three Phosphorus Vertexes

摘要

The reaction of borane-based anions with PCl_3 in the presence of basic reagents as deprotonation agents leading to phosphaboranes/carboranes was pioneered by Todd and Little several years ago. There is a current interest in the syntheses of phosphacarbonans, stable structural analogues of carboranes.
