Abstract
A series of bisphosphorylimides based on the reaction sequence of Atherton-Todd and Staudinger reaction were synthesized. These bisphosphorylimides containing phosphorus in different chemical environments, while the reaction sequence is using mild conditions and more over can be synthesized in an one-pot procedure. The molecular structures were revealed by nuclear magnetic resonance spectroscopy and x-ray crystallography. The stability of the bisphosphorylimides against hydrolysis and thermal influences was tested which allows an initial estimation about the usage as flame retardant.
