Versuchsvorschrift
A solution of 5.80 g (21.9 mmol) of triphenylphosphine and 8.00 g (43.8 mmol) of cyclohexylmethyl bromide in 30 ml of toluene was heated at reflux for 4 days. After removal of solvent in vacuo, the residue was taken up in tetrahydrofuran and filtered to give 6.96 g (37%) of the desired compound.
