experimental part, p. 759 - 770 (2010/01/07)
CARBAMIC acid 3,4-dichlorophenyl sulfonyl methyl ester was prepared, interaction with different amines yielded a series of N-substituted-N'-3,4- dichlorophenyl sulfonylureas. Chemical structure was confirmed on the basis of elemental analysis, MS, IR and 1HNMR spectroscopy. A pronounced herbicidal activity against Echinoocloa crus-galli L. Beauv (barnyard grass ) was attained by sulfonylureas bearing pyridyl, benzoic acid-4-amino-and butyl moieties. Meanwhile, the corresponding phytotoxicity to Oryza straiva L. (rice) was relatively low.
