Abstract
Abstract Herbicidal allophanimidic acid esters of the formula: WHERE R1, R2, R4 and R5 are selected from hydrogen and certain organic radicals, at least one of them being an organic radical; R3 is selected from hydrogen and certain organic radicals; R6 is selected from certain organic radicals; and X1, X2, and X3 are selected from oxygen and sulfur; AND SALTS OF THE ABOVE COMPOUNDS IN WHICH R3 is hydrogen. Preparation of the compounds by carbamoylation of OR BY REACTION OF AMMONIA OR AN AMINE WITH WHERE Y is -SCH3, -Cl, An exemplary compound: methyl N-dimethylcarbamoyl-4-tertbutylthioallophanimidate.
