Procedure

A stirred mixture of undecyl-triphenyl-phosphonium bromide (45.7 g), methanol (300 ml) and 2M sodium hydroxide solution (300 ml) was heated at 50° C. for 3 hours and then concentrated under vacuum until the oily product solidified. The solid was washed with water, dried and recrystallised from petroleum spirit to give diphenyl-undecylphosphine oxide, m.p. 69° C.
