反应详情

Under a nitrogen atmosphere, a solution of 10.0 grams (0.049 mole) of 2-chlorophenylmethyl bromide and 13.0 grams (0.050 mole) of triphenylphosphine in about 100 mL of toluene was heated at reflux for about 18 hours. The reaction mixture was cooled, and a solid was collected by filtration. The solid was washed with toluene and dried under vacuum, yielding 22.8 grams of 2-chlorophenylmethyltriphenylphosphonium bromide, mp>250° C.
