Colorless to light yellow liqui
Chlorodiphenylphosphine is used to introduce the diphenylphosphinyl moiety by aryl ortho-lithiation. It is also used as an intermediate to make antioxidants, flame retardants, stabilizers, catalysts, photoinitiators, and optical brighteners. Used as a halogenation reagent for the conversion of alcohols into halides, in the preparation of solid-phase reagent for the conversion of alcohols to alkyl halides.
The specific synthesis steps of Chlorodiphenylphosphine are as follows: In a sealed NMR tube filled with argon,Dissolve Ph2P (O) H (0.05 mmol) in 0.5 mL of tetrahydrofuran,Add acetyl chloride (the amount of acetyl chloride added is 1.2 times the equivalent of Ph2P (O) H),The mixture was reacted at 100 ° C for 12 hours with a yield of 99%.

This air-sensitive, pale yellow lachrymatory liquid is purified by careful fractional distillation and discarding the lower boiling fraction which contains the main impurity PhPCl2 (b 48-51o/0.7mm), and checking for impurities by NMR.
