Various thiophenecarboxylates carrying a 2-trifluoromethyl, 2-(1,1-difluoroalkyl) or 2-polyfluoroalkyl group are synthesized conveniently from reaction of α-fluoroalkyl ketones 1, aldehydes 2 or ethyl α-fluoroalkylacetates 3 with methyl (or ethyl) 2-sulfanylacetates 4. A possible reaction pathway is suggested.
