phosphonous dichloride, which reacted with lithium (2,4,6-tri-t-butylphenyl)phosphide to give 1,2-bis[3,5-di-t-butyl-2-(2,4,6-tri-t-butylphenyl)phosphinidenephosphino}phenyl]ethane; the photolysis of the compound gave E-bis(2,4,6-tri-t-butylphenyl)diphosphene and an internal Z-diphosphene; the tungsten complex of the latter was analyzed by X-ray crystallography.
空间位拥挤溴苯,1,2-双(2-溴-3,5-二-吨丁基苯基)乙烷,制备并转化成相应的膦二氯化物,其与锂反应(2,4,6-三吨丁基苯基)磷化物,得到1,2-双[3,5-二-吨-丁基-2 - (2,4,6-三-吨丁基苯基)phosphinidenephosphino}苯基]乙烷; 该化合物的光解,得到ë -双(2,4,6-三-吨丁基苯基)diphosphene和内部Z-diphosphene; 通过X射线晶体学分析后者的钨配合物。
