Triphenyl phosphite → HCID 70457302, compound

Participants

Reaction Steps

Chlorine was added to a solution of 20.0 gm of triphenyl phosphite in 100 ml of methylene chloride at -15° to -20° C. until a faint chlorine color persisted in the mixture. After warming the product solution to room temperature it was studied by 31P nmr. The 31P nmr spectrum of an aliquot of the product solution initially indicated 1 component having a signal at -3.7 ppm relative to the phosphoric acid 31P nmr resonance signal. That signal descreased in intensity with time as a new signal at 22.7 ppm increased in intensity. From the 31P nmr data, the half-life for the initial product was determined to be about 8 hours.
