Isolation of donor-stabilized N-silylphosphoranimine cations and the discovery of an ambient temperature route to Poly(alkyl/aryl)phosphazenes

This account describes the formation of nitrogen and phosphorus donor-stabilized phosphoranimine cations from N-silylphosphoranimines. A novel phosphine-mediated dehalogenation reaction is also described, as well as the discovery of an ambient temperature route to poly(alkyl/aryl)phosphazenes.
