It was discovered that phosphazenyl phosphines (PAPs) can be stronger P‐superbases than the corresponding Schwesinger type phosphazene N‐superbases. A simple synthetic access to this class of PR3 derivatives including their homologization is described. XRD structures, protonaffinities (PA), and gas‐phase basicities (GB) as well as calculated and experimental pK values in THF are presented. In contrast

A thermosetting polyamide foam prepared by reacting a polyisocyanate compound with a polyester polycarboxylic acid using a compound having a P=N bond as a catalyst under conditions of an NCO index of not less than 1.6. The polyamide foam is excellent in heat resistance (thermal decomposition resistance) and moldability, and is applicable for heat-resistant vibration dampers, heat-resistant sound-absorbing materials and heat-resistant cushioning materials.
