| description | Novel N-substituted imido-dicarboxylic acid diaryl ester compounds of the general formula (I) in which R1 represents an optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic, heterocyclic radical and R2 and R3 can be identical or different and represent an optionally substituted aryl radical, and a process for their preparation characterized in that a carbamic acid aryl ester of the general formula: R1-NH-CO-OR2 (II) in which R1 and R2 have the abovementioned meanings, is reacted with a carbonic acid aryl ester halide of the general formula X-CO-OR3 (III) in which R3 has the abovementioned meaning and X represents a halogen atom, optionally in the presence of a diluent, optionally at a temperature between 100 DEG and 300 DEG C. The new compounds (I) can be used as intermediate products for the preparation of known herbicidal active compounds from the 1,3,5-triazine,2,4-(1H,3H)-dione series. |
