3,5-BIS(TRIFLUOROMETHYL)ANISOLE Use and Manufacturing

Preparation of 3, 5-bis(trifluoromethyl)anisole From 1-bromo-3, 5-bis(trifluoromethyl)benzene. 25 g of 1-bromo-3, 5-bis(trifluoromethyl)benzene (85 mmol) are introduced into a mixture of 366 mg of copper(I) bromide (CuBr, 3 mol percent), 1.57 g of 18-crown-6 (7 mol percent) and 92.3 g of sodium methanolate solution in methanol (30percent strength) (precursor concentration 21percent) and heated to 105° C. After the conversion, determined by GC, it is >97percent (total of 22 h), the reaction mixture is added to 175 g of water. The mixture is brought to pH 5-6 by metering in hydrochloric acid and is then filtered through decalite. The mixture if extracted twice with 150 g of dichloromethane each time. Vacuum fractionation of the combined organic phases results in 16.5 g of 3, 5-bis(trifluoromethyl)anisole (68 mmol, 79.4percent), GC purity >98.5percent a/a.
