Arylamines add to the carbon atom at position 5 of 1-aryl-4aroyl-5-methoxycarbonyl-2,3-dihydro-2,3-pyrrolediones with the formation of 1-aryl-5-arylamino-4-aroyl-5-methoxycarbonyl-3-hydroxy-2,5-dihydro-2-pyrrolones.The latter react with an excess of the a
MECHANISMS OF THE REACTIONS OF 1,3-DICARBONYL COMPOUNDS WITH NUCLEOPHILIC REAGENTS. I. FEATURES OF THE MECHANISM AND CATALYSIS OF THE ADDITION OF AROMATIC AMINES TO THE ENOLIZED CARBONYL GROUP OF AROYLPYRUVIC ESTERS

The kinetics of the reaction of aroylpyruvic esters with aniline, p-toluidine, and p-anisidine in 80percent ethanol in the range of pH 2.6-5.45 were investigated by a spectrophotometric method.At pH values below 4 the reaction rate is controlled by the stage of addition of the amines to the aroylpyruvic esters.With increase in the pH value the dehydration stage becomes rate-determining.The addition stage is characterized by specific acid catalysis.
