Triphenylphosphine phenylimide is the

Ph = C6H5). It is a white solid that is soluble in organic solvents. The compound is a prototype of a large class of Staudinger reagents, resulting from the Staudinger reaction
.

The phosphine imides were first prepared in the laboratory of Nobelist

phenylazide. [1]

Ph3P + N3Ph → Ph3P=NPh + N2

X-ray crystallography establishes that the P-N-C angle is bent (130.4°) and the P-N distance is 160 pm.[2]
