The protonation chemistry of trichlorophosphazene (R-1-N=PC3) with sulfonic acids ((RSO3H)-S-2) was found to be affected by the N-substituents R-1, yielding bis(sulfonyl)imides containing both R-1 and R-2, and mixed sulfonylphosphonyl imides containing either R-1 or R-2. Tn 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.
