4-Trifluoromethylphenol Usage And Synthesis

Preparation method	Chlorosilane and bromotrifluoromethane at-59℃form trifluoromethylsilane. Trifluoromethylsilane and benzoquinone in the presence of catalyst form 4-triethylsiloxy-4-trifluoromethyl-2,5-cyclohexadien-1-ketone which is reduced by zinc powder to p-trifluoromethylphenol with a yield of 71%. This method avoids the use of hydrofluoric acid in the traditional process but should be carried out under anhydrous conditions.If there were water trifluoromethyl silane would rapidly become silanol under the effect of water and alkali. The catalyst used in the reaction is alkali of which the strength has nothing to do with the catalytic activity. By now the role of catalyst is still unknown but the reaction can not proceed without catalyst.
