Workup

  1. 1
    Temperatureat reflux for 19 hours

Procedure

A solution of 30.3 g (0.1 mole) of 4-triflyl-alpha-bromotoluene and 28.8 g (0.1 mole) of triphenylphosphine in xylene is heated at reflux for 19 hours. 4-Triflylbenzyltriphenylphosphonium bromide is then isolated by filtration, washed with additional portions of xylene, and dried.
