| Chlorodiphenylphosphine Usage And Synthesis |
Chemical Properties | Colorless to light yellow liqui | Uses | 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. | Synthesis Reference(s) | Journal of the American Chemical Society, 77, p. 3526, 1955 DOI: 10.1021/ja01618a030 | Flammability and Explosibility | Nonflammable | Purification Methods | 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.
