The first examples of arylphosphonium salts containing a dicarba-closo-dodecaborane(12) (closo-carborane) are reported; in contrast to the 1,12-carborane derivative, the 1,2- and 1,7-isomers undergo a facile deboronation reaction in polar solvents to afford the corresponding nido-carborane phosphonium zwitterions.
报道了含有二卡巴基-双十二碳
硼烷(12)(
氯基碳烷)的芳基salts盐的第一个例子;与1,12-碳
硼烷衍
生物相反,1,2-和1,7-异构体在极性溶剂中容易进行脱
硼反应,从而得到相应的Nido-碳
硼烷phospho两性离子。
