Phenyl phosphorochloridite

Diphenyl phosphorochloridite is a colorless, viscous liquid with a pleasant smell it shows the following physical properties b.p. 115° at 0.5 mm., 147° at 4 mm., 172° at 11 mm.,iand295°at731mm. = 1.5776 d J = 1.221. Inasmuch as diphenyl phosphorochloridite disproportion-ates to triphenyl phosphite and phenyl phosphorodichlori-dite, it is necessary to distill the product immediately before use ...
