Spectra and structure of salts of triphenylphosphine-N-phenylimine and its complexes with phenols

1. The IR spectra of salts of triphenylphosphine-N-phenylimine and its complexes with phenol were investigated. 2. The aggregate of spectral data obtained permits characterization of the structure of salts of phosphinimines as mesomeric with a pronounced phosphonium structure. 3. The interaction of triphenylphosphine-N-phenylimine with phenol and p-bromophenol leads to the formation of complexes with a hydrogen bond with a 1∶1 composition, which were isolated in crystalline form. 4. In the complex of pentachlorophenol with triphenylphosphine-N-phenylimine, the spectral data indicate a strong acid-base interaction, which leads to protonation of the phosphinimine molecule.

Preparation of some unsymmetrigal diarylimines of tetraphenylmethylenediphosphine

Some tetraphenylmethylenediphosphine (N-phenyl-N′-aryldiimines) were synthesized by the reaction of tetraphenylmethylenediphosphine with aryl azides.

Some properties of tetraphenylmethylenediphosphine di(N-phenylimine)

1. A study was made of the reaction of tetraphenylmethylenediphosphine di(N-phenylimine) (I) and its metal derivatives with CH3I. 2. Only the monomethiodide is formed when diimine (I) is reacted with CH3I.
