반응 단계
A mixture of triphenylphosphine (15.7 g) and carbon tetrabromide (9.93 g) in dry dichloromethane (100 mL) is cooled to 0° C. and stirred for 30 minutes. A solution of 2,4-dibenzyloxybenzaldehyde (4.76 g) in dichloromethane (30 mL) is added and the solution stirred at 0° C. for 2 hours. The solution is treated with pentane to precipitate triphenylphosphine oxide. The filtrate is evaporated to give 1-(2,4-dibenzyloxyphenyl)-2,2-dibromoethylene as a yellow oil (4.85 g, 67%).
