MONOAMIDATION REACTIONS OF DIGLYCOLIC ACID WITH ANILINES
Keywords:
Diglycolic acid, orthoboric acid, monoamide, diamide, arylamide, anilines, toluene, ortho-xyleneAbstract
The reactions of diglycolic acid with anilines were carried out under the catalysis of orthoboric acid. Diglycolic acid is a dicarboxylic acid, it reacts with amine in 1:1 and 1:2 molar ratios, and mono- and diamide products are formed. In order to synthesize monoamides, diglycolic acid and anilines were reacted with different amounts of catalyst and different times. Reactions of diglycolic acid with 8-substituted anilines ware taken at 25 mol% of the starting acid carried out for 5 hours and 12.5 mol% for 10 hours, and monoarylamides were synthesized.
