The synthesis of a series of polyfluoromethyl-substituted pyrimidines and pyrazoles bearing potential for further functionalization of the hydroxymethyl group prepared from the fluoroalkyl-containing enones with isothioureas, amidine and hydrazines, is reported. We investigated the deoxyfluorination of hydroxymethyl group in polyfluoromethyl containing pyrazoles and obtained di- and trifluoromethyl

An efficient approach for the synthesis of 3-(polyfluoroacyl)pyruvaldehydes dimethyl acetals (1,1-dimethoxy-4-polyfluoroalkyl-butan-2,4-dions) from 1,1-dimethoxyacetone and polyfluorinated carboxylic acid esters has been developed. The procedure includes the Claisen type condensation of the starting materials by means of calcium hydride in methanol, followed by isolation of copper complexes of the
