Abstract

Common bases (alcoholate, dimsyl anion or amide) are able to deprotonate trifluoromethane to form a trifluoromethyl anion equivalent. In this reaction DMF plays a crucial role of stabilisation. Trifluoromethyl aryl alcohols, ketones or sulfides can be obtained in good yields with the new reagent CF3H/Base/DMF.
