Conclusions
The reaction of oxazaphospholanes with acid chlorides of trivalent phosphorus takes place with the cleavage of exo- or endocyclic P-N bonds. The opening of the ring produces diphosphorylated alkanolamines, which are converted as a result of disproportionation into 1,3,2-diheterophospholanes, the latter being products of the exchange of exocyclic substituents.
