Versuchsvorschrift
Mix triphenylphosphine (200 g, 0.76 mol) and bromomethyl-cyclohexane (400 g, 2.26 mol) under an argon atmosphere and stir 16 h at 165° C. Pour the reaction mixture into 750 mL toluene and stir until the suspension reached ambient temperature. Filter and wash the product with diethylether and dry under vaccum to get 332.3 g pure product. MS (m/e): 359.0 (M+H).
