Abstract

A series of phosphine-stabilized phosphoranimine cations [R3P· PR′ 2 NSiMe3]+, which can be regarded as derivatives of the proposed transient reactive intermediate [PR′ 2 NSiMe3]+ in the thermal condensation polymerization of phosphoranimines (R′′ O) PR′ 2 NSiMe3 to form poly (alkyl/arylphosphazenes)[PR′ 2 N] n at 180− 200° C, have been prepared. The bromide salts [R3P· PR′ 2 NSiMe3] Br [R′= Me ([6]+), OCH2CF3 ([8]+); ...
