ABSTRACT
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 [1]HNMR 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
