PROCESSO PARA A PREPARACAO DE 1-AMINO-1,3,5-TRIAZINA-2,4(1H,3H)-DIONAS

A process for the preparation of a 1-amino-1,3,5-triazine-2,4(1H, 3H)-dione compounds comprising the steps of reacting an N-substituted imido-dicarboxylic acid diaryl ester with an isothiosemicarbazone at a temperature of between 50 DEG and 150 DEG C. to form a 1-alkylidene-amino-1,3,5-triazine-2,4(...

Zusammenfassung:A process for the preparation of a 1-amino-1,3,5-triazine-2,4(1H, 3H)-dione compounds comprising the steps of reacting an N-substituted imido-dicarboxylic acid diaryl ester with an isothiosemicarbazone at a temperature of between 50 DEG and 150 DEG C. to form a 1-alkylidene-amino-1,3,5-triazine-2,4(1H, 3H)-dione reaction product; and thereafter, hydrolyzing the reaction product in an acid medium. The reaction product need not be separated from the reaction mixture before the hydrolysis step. Certain novel 1-amino-1,3,5-triazine-2,4(1H, 3H)-dione compounds are provided. The compounds are useful as herbicides.
