Synthesis

1079-66-9

4020-99-9

The general procedure for the synthesis of diphenylmethoxyphosphine from diphenylphosphonium chloride is as follows: 210 g (6.56 mol) of anhydrous methanol was cooled to -15°C under nitrogen protection. At this temperature, 200 g (0.907 mol) of diphenylphosphonium chloride was vigorously stirred and slowly added dropwise. Subsequently, 18 g (1.06 mol) of ammonia was passed. After cooling was withdrawn, stirring of the reaction mixture was continued for 10 h. Upon completion of the reaction, the product was separated by diafiltration. The filtrate was distilled under reduced pressure to remove methanol and excess ammonia. The residue was filtered by pumping through a glass sand core funnel to give 143 g of crude diphenylmethoxyphosphine in 73% yield of the theoretical value.
