Abstract

The protonation chemistry of trichlorophosphazene (R¹-N=PCl₃) with sulfonic acids (R²SO₃H) was found to be affected by the N-substituents R¹, yielding bis(sulfonyl)imides containing both R¹ and R², and mixed sulfonylphosphonyl imides containing either R¹ or R². In the formation of the latter a hitherto unobserved chemistry occurred. An intramolecular 'imine SN₂' mechanism was proposed to rationalize the reactions observed. (C) 2000 Elsevier Science S.A.
