Novel herbicidal thiadiazoles of the formula:
(wherein: R1 represents a group Ra, -S(O)nRa or-SO2NRaRb, where Ra and Rb, which may be the same or different, each represent hydrogen cycloalkyl of 3 to 7 carbon atoms, alkenyl or alkynyl of 2 to 6 carbon atoms, phenyl, phenylalkyl of 7 to 10 carbon atoms, or alkyl of 1 to 10 carbon atoms, any phenyl or alkyl group present being optionally substituted by one or more halogen atoms, cyano groups, alkoxy or alkylthio groups of 1 to 4 carbon atoms, or phenoxy groups, or Ra and Rb together form an alkylene chain of 2 to 6 carbon atoms, and n represents 0, 1 or 2;
X represents oxygen or sulphur;
Z represents a group -NR°Rd: and
Y represents a group -NReRf or a group -N=CReRf; where RC, Rd, Re and Rf, which may be the same or different, each represent a group as defined for Ra, or a carboxy, alkoxy, alkoxycarbonyl, acyl, acyloxy, alkylsulphonyl, cyano, formyl, amido, or heterocyclyl group, any alkyl moiety of which is of 1 to 4 carbon atoms); and the acid addition salts thereof, compositions containing them and processes for their preparation.
式中的新型除草噻二唑:
其中R1代表基团Ra、-S(O)nRa或-SO2NRaRb,其中Ra和Rb可以相同或不同,各自代表3至7个碳原子的氢环烷基、2至6个碳原子的烯基或炔基、苯基、7至10个碳原子的苯基烷基或1至10个碳原子的烷基、存在的任何苯基或烷基任选被一个或多个卤素原子、氰基、1 至 4 个碳原子的烷氧基或烷硫基或苯氧基取代,或 Ra 和 Rb 共同形成 2 至 6 个碳原子的亚烷基链,且 n 代表 0、1 或 2;
X 代表氧或硫;
Z 代表基团 -NR°Rd
其中 RC、Rd、Re 和 Rf 可以相同或不同,各自代表一个如 Ra 所定义的基团,或一个羧基、烷氧基、烷氧羰基、酰基、酰氧基、烷基磺酰基、氰基、甲酰基、氨基或杂环基,其中任何烷基的碳原子数为 1 至 4);以及它们的酸加成盐、含有它们的组合物和制备它们的工艺。
