Conclusions
The reaction of 2-N-phenylamino-1,3,2-dioxaphospholane with phenyl isocyanate proceeds to give N,N-bis(1,3,2-dioxaphospholanyl)phenylamine and diphenylurea due to the reversible disproportionation of the starting amidophosphite to N,N-bis(1,3,2-dioxaphospholanyl)phenyl-amine and aniline.
