Abstrakt: 1.Methyl esters of fluorine-containing a-ketoacids with methylamine, regardless of the nature of the solvent, give addition products at the a-keto group and products of aminolysis of the ester group.2.Esters of fluorine-containing a-ketoacids react regiospecifically with diethylamine at the ester group, giving N,N-diethylamides of a-hydroxy-a-methoxyfluorocarboxylic acids in aprotic media and diethylammonium salts of fluorine-containing a,a-dihydroxyfluorocarboxylic acids in proton donor media; upon heating, the diethylammonium salts eliminate water with the formation of diethylamides.
