2,3,5,6-Tetrafluorophenol → HCID 18332211, compound

Participants

Reaction Steps

3.32 g (20 mmol) of 2,3,5,6-tetrafluorophenol are dissolved in 50 ml of toluene, and 8 ml of n-butyllithium (2.5 M in hexane) are added at 0° C. After warming to room temperature, the solution is stirred for a further 2 hours. Then 4.3 g of (chloromethyl)triethoxysilane (20 mmol) are added dropwise and the reaction mixture is boiled under reflux for 6 hours. The resulting suspension is filtered and the solvent is stripped off in vacuo. The pale yellow liquid which remains is subjected to fractional distillation.
