Phosphinimines, alkylation

Phosphazene copolymers have also been prepared by the thermolysis of equimolar mixtures of the phenyl/alkyl and dialkyl substituted P-trifluoroethoxy-phosphinimines.

By using type II-B aniline-phosphinimines (Scheme 20), various bisalkyl rare-earth metal complexes were synthesized. All complexes 52-58 were obtained by the reaction of the corresponding aniline-phosphinimines HL12-HL15 with [Ln(CH2SiMe3)3(THF)2] (Ln = Sc, Y, Lu) in toluene via alkyl elimination (Scheme 21) [54]. 

Organic azides react with tertiary alkyl(aryl)phosphines to give iminophos-phoranes (phosphinimines) ... 

Some bond dissociation energies corresponding to the dissociation of phosphoryl, thiophosphoryl, and N-alkyl (phosphinimine) compounds are shown in Table 2. In this last case dissociation gives rise to the trivalent PX3 compound and the radical NR. Some of these values have been calculated from the difference between the heats of formation of APX3 and PX3 compounds, whilst others are derived from direct measurements of heats of oxidation.
