The reaction of transient phosphinidene pentacarbonyltungsten complexes with phosphaalkenes at 120°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°C into the symmetrical 1,2-diphenyl derivative via an unknown mechanism.
瞬时亚膦五羰基钨络合物与膦烯在 120°C 的甲苯中发生反应,直接生成相应的未络合的 1,2-二膦环烷。由此获得的 1-氯-2-苯基-1,2-二膦环烷在 120°C 进一步加热后,通过未知的机理转化为对称的 1,2-二苯基衍生物。
