| abstract | ABSTRACT OF THE DISCLOSURE Herbicidal 1-amino-1,3,5-triazine-2,4(1H, 3H)-diones of the general formula (I) are obtained in good yields if an N-substituted O-aryl N-chlorocarbonyl carbamate of the general formula (II) is reacted with an isothiosemicarbazone of the general formula (III) or hydrohalide thereof, (R1 to R4 in formulae (I) to (III) having the meanings given in the description), at a temperature between 0 and 50°C, in the presence of an acid-binding agent, the open-chain intermediate products formed thereby are than heated (if appropriate without intermediate isolation), in a second stage, to a temperature between 50 and 150°C and, finally in a third stage, the 1-alkylldenosmlno-1,3,5 triazino-2,4(1H, 3H)-dione formed thereby is hydrolyzed if appropriate again without intermediate isolation) in an acid medium. |
