Triphenyl phosphite → HCID 459171, compound

Participants

Reaction Steps

32.5 g (0.24 mole) of phosphorus trichloride is added dropwise, with stirring, to a mixture, cooled to 0° to 5° C, of 155.2 g (0.5 mole) of triphenylphosphite and 10.0 g of hexamethylphosphoric acid triamide. The reaction mixture is subsequently heated to room temperature and stirred at this temperature for a further 4 hours. On vacuum distillation of the reaction mixture there is obtained 110 g (61.1% of theory relative to phosphorus trichloride) of diphenylchlorophosphite, b.p. 170°-172° C/11 Torr.
