瞬时膦亚基五羰基钨络合物与磷烯烃在 120℃下在甲苯中反应,直接生成相应的未络合的 1,2-二膦。由此获得的 1-氯-2-苯基-1,2-二磷杂环在 120 o C 进一步加热时通过未知机制转化为对称的 1,2-二苯基衍生物
The reaction of transient phosphinidene pentacarbonyltungsten complexes with phosphaalkenes at 120 o C, in toluene directly yields the corresponding uncomplexed 1,2-diphosphiranes. A 1-chloro-2-phenyl-1,2-diphosphirane, thus obtained, is transformed upon further heating at 120 o C into the symmetrical 1,2-diphenyl derivative via an unknown mechanism
