In the chemistry of squaric acid, we find first that 1, 3-diaryl iso- squarylium amide can react with HMPA and other carboxylic amides. Fifteen asymmetric amides of squaric acid containing aryl and alkyl are synthesized. This novel reaction can be used for effective preparation of asymmetric amide of squaric acid containing aryl and dimethylamino, methylamino, ethylamino. The possible mechanism of reaction is discussed preliminarily.
