Triphenyl phosphite → HCID 131711934, compound

Participants

Reaction Steps

To a solution of 1.6 gm of bromine in 30 ml of methylene chloride at -45° C. was added a solution of 3.1 grams of triphenyl phosphite in 5 ml of methylene chloride. After warming the product solution to room temperature it was studied by 31P nuclear magnetic resonance (nmr). The 31P nmr spectrum initially indicated 1 major component having a signal at -3.7 ppm relative to the phosphoric acid 31P resonance signal. This signal decreased in intensity with time as a signal at 22.4 ppm increased in intensity. From the 31P nmr data the half-life (t 1/2) for the initial product was determined to be about 39 hours.
