Abstract
A variety of carbamoylimidazoles were synthesized from 1, 2, 3, 4-tetrahydroquinolines, 1, 2-dihydroquinolines, benzomorpholines and 1, 2, 3, 4-tetrahydro-2-quinoxalinones and their herbicidal activity was examined. Substituents appeared to be important for their herbicidal activity. Highly active compounds were obtained when they were crowded around carbamoylimidazole linkages. Of these compounds, N-(2, 2-dimethyl-6-chloro-1, 2, 3, 4-tetrahydroquinoline) carbonylimidazole was tested against some weeds, and the test showed that it was a promising new herbicide with a wide spectrum.
