The invention provides herbicidal triazolesulphonamides, processes for their preparation and compositions containing them, the compounds being of the formula:
and the salts thereof, where Ra represents hydrogen and Rb represents a group R³CONHCR²=CR¹-, or Ra and Rb together represent a chain of formula
-C(R³)=N-C(R²)=C(R¹)- or
-C(=Y)-N(R⁶)-C(R²)=C(R¹)-, where R¹, R² and R³, which may be the same or different, each represent hydrogen, hydroxy, mercapto, halo, cyano, amino, alkylamino, dialkylamino, or substituted or unsubstituted alkyl, aryl, aralkyl, alkoxy or alkylthio, Y is oxygen or sulphur, and R⁶ is hydrogen or a substituted or unsubstituted alkyl or aryl group; or R¹ and R² together represent -CH=CH-CH=CH- or -(CH₂)n- where n is 3, 4 or 5; R⁴ represents substituted phenyl or a substituted or unsubstituted aralkyl or heteroaryl group; and R⁵ represents hydrogen, acyl, carboxy, lkoxycarbonyl, alkylsulphonyl, or a substituted or unsubstituted alkyl, alkenyl, alkynyl, aryl or aralkyl group, or a group of the formula:
where Ra and Rb are as defined hereinbefore.
该发明提供了除草三唑磺胺类化合物,以及它们的制备方法和含有它们的组合物。这些化合物的结构如下:其中Ra代表氢,Rb代表一个基团R³CONHCR²=CR¹-,或者Ra和Rb一起代表一个结构为-C(R³)=N-C(R²)=C(R¹)-或-C(=Y)-N(R⁶)-C(R²)=C(R¹)-的链,其中R¹、R²和R³分别代表氢、羟基、硫醇基、卤素、氰基、氨基、烷基氨基、二烷基氨基,或取代或未取代的烷基、芳基、芳基烷基、烷氧基或烷硫基;Y代表氧或硫,R⁶代表氢或取代或未取代的烷基或芳基;或者R¹和R²一起代表-CH=CH-CH=CH-或-(CH₂)n-,其中n为3、4或5;R⁴代表取代的苯基或取代或未取代的芳基烷基或杂环芳基基团;R⁵代表氢、酰基、羧基、烷氧羰基、烷基磺酰基,或者取代或未取代的烷基、烯基、炔基、芳基或芳基烷基,或者一个结构为的基团,其中Ra和Rb如上定义。
