    摘要： New herbicidal compounds are provided having the formula wherein Y is oxygen or sulfur; R1 and R2 are each independently a C1-4 hydrocarbyl group, unsubstituted or substituted with one or more halogen, haloalkyl, hydroxy, alkoxy, carboxy, amido, cyano or amino groups; or R1 and R2, together with the carbamoyl nitrogen atom to which they are attached, form a nitrogen-containing five or six membered ring, the ring being optionally interrupted by an ethereal oxygen atom and unsubstituted or substituted with one or more hydroxy, amido, cyano, amino or C1-8 alkyl, alkenyl, alkynyl, cycloalkyl, arylalkyl, alkoxy, aminoalkyl or haloalkyl groups; and R3 is hydrogen, halogen, or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, cycloalkylalkenyl, aryl, arylalkyl, alkylthio or arylalkylthio group that is unsubstituted or substituted with one or more halo, hydroxy, alkoxy, acetyloxy, benzoyloxy, alkoxycarbonyl, silyl or alkylsilyl groups; or an agronomically acceptable acid addition salt or metal complex of such compound.
