| titleOfInvention | PROCEDURE FOR THE PREPARATION OF IMIDAZOISOINDOLDIONAS. |
| abstract | Preparation process of imidazoisoindoldiones, of herbicidal effect, of formula: **(See formula)** where X is H, CH3, NO2, Cl, OCH3 or SCH3; R1 is C1-C4 alkyl and R2 is C1-C6 alkyl, C3-C6 cycloalkyl, C2-C4 alkenyl phenyl, halophenyl or benzyl; and when and R1 and R2 are taken together they can form C3-C6 cycloalkyl optionally substituted with methyl, characterized in that it comprises carrying out a cyclization reaction by heating a compound of formula: **(See formula)** wherein X, R1 and R2 are as described above, at a temperature of about 80-150ºC, in the presence of an inert organic solvent and an alkali metal hydride reactant, alkali metal hydroxides, alkali metal oxides, tertiary amine, 1,5-diazobicyclo [3.4.0] -51,5-diazobicyclo [5.4.0] undiceno-5; 1,4-diazobicyclo [2.2.2] octane; tetramethylguanidine, potassium fluoride, quaternary ammonium hydroxides, strongly basic ion exchange resins, or aromatic sulfonic acids; and removing any water, formed during the cyclization of the phthalimidocarboxamide detailed above, from the reaction mixture, thus obtaining the imidazoisoindoldiones.
