Methanol → Triphenylphosphine Oxide

Participants

Reaction Steps

To a mixture of methanol (125 ml), triphenylphosphine sulfide (7.5 g) and aqueous 2.5% sodium hydrogen carbonate (25 ml) is added aqueous 14.3% sodium hypochlorite (125 ml) at 10° C. to 15° C., and the mixture is stirred for 1 hour at the same temperature. The reaction mixture is diluted with water (500 ml), and the separated crystals are collected by filtration, washed with water and dried to give triphenylphosphine oxide (6.5 g). m.p. 154°-157° C.
