反应详情

Dissolved in 50 ml of toluene were 7.65 g (26.5 mmol) of 5-(3-bromopropyl)-1,2,3-trimethoxybenzene and 6.9 g (26.5 mmol) of triphenylphosphine, followed by heating under reflux for 23 hours. The reaction mixture was allowed to cool down to room temperature. The supernatant was thereafter removed by decantation, whereby 7.46 g of crude triphenyl[3-(3,4,5-trimethoxyphenyl)propyl]phosphonium bromide were obtained as colorless oil (yield: 51%). The crude oil was used in the next reaction without purification.
