A new type of stepwise addition of alkylisocyanates 2a,b to two phosphorus atoms of methylenephosphinophosphorane 1 leads to the formation of unusual compounds 4a,b and 5a,b with two phosphorus atoms of different coordination number λ4P+, λ6P− and opposite formal charge.
一种新型的逐步添加alkylisocyanates的图2a,2b至methylenephosphinophosphorane的两个磷原子1个导致形成异常的化合物的图4A,4B和图5A,B具有不同配位数的两个磷原子λ 4 P +,λ 6 P -和反对正式指控。

Insights into the Staudinger Reaction: Experimental and Theoretical Studies on the Stabilization ofcis-Phosphazides
The Staudinger-model reaction H3P (1) + HN3 (2) H3P=NH (5) + N2 (6) has been investigated at the CCSD(T)/6-31G**//MP2(Full)/6-31G* level. Primary products formed in this reaction are the phosphazides H3P=N–N=NH (3) which exist as trans and cis isomers. In contrast to some previous assumptions, cis-3is 8.2 kcal mol−1 more stable than trans-3 but decomposes rather easily into the expected products H3P=NH
