Abstract

It is shown that the basic properties of arylamides of diarylglycolic acids are determined not only by the nature of the aryl radicals of the acid part of the molecule, but also by the extent to which hydrogen atoms of the amino groups are substituted. Formation of carbonium salts of arylamides is considerably influenced by the nature of the solvent. Intramolecular condensation of tertiary arylamides of 4, 4′-dimethoxy- and 4, 4′-dimethylbenzylic acids gives a number of new 1-alkyl (aryl)-3, 3-diaryloxindoles. Ethyl N-n-propyl- and N-isobutyloxanilate and N,N-diethylamide-4, 4′-dimethoxybenzylate are described for the first time.
