2-Diphenylphosphanyl-1,3,2-diazaphospholidines were prepared via metathesis from 2-chloro-1,3,2-diazaphospholidines and LiPPh2. For some of the products, symmetrisation to tetraphenyldiphosphane and 2,2′-bis-1,3,2-diazaphospholidinyls was observed. Most of the derivatives were characterised by single-crystal X-ray diffraction, which showed that all compounds studied feature elongated exocyclic P–Cl
2-二苯基膦酰基-1,3,2-二氮杂磷脂通过复分解从 2-氯-1,3,2-二氮杂磷脂和 LiPPh2 制备。对于一些产品,观察到对称化为四苯基二膦和 2,2'-双-1,3,2-二氮杂磷脂。大多数衍生物通过单晶 X 射线衍射表征,这表明所有研究的化合物分别具有拉长的环外 P-Cl 或 P-P-键。这种键延长的程度在 P-膦酰基取代的物种中类似,在 P-氯衍生物中不如相应的 CC-不饱和 1,3,2-二氮杂磷烯明显。
