실험 절차

A suspension of the carbo-t-butoxymethyl triphenylphosphonium bromide (55.8 g, 122 mmol) in water (400 ml) was treated with sodium hydroxide (4.7 g, 117 mml) in water (100 ml). The mixture was stirred for 16 hours and the solid collected to give 43.7 g (95% of theory) of carbo-t-butoxymethylene triphenylphosphorane.
