Triphenylphosphine phenylimide is the organophosphorus compound with the formula Ph3P=NPh (Ph = C6H5).

This white solid is soluble in organic solvents.

The phosphanimines were first prepared in the laboratory of Nobelist Hermann Staudinger.

His synthesis involved the direct reaction of triphenylphosphine with phenylazide.

[1] X-ray crystallography establishes that the P–N–C angle is bent (130.4°) and the P–N distance is 160 pm.
