N-([1,2,4]TRIAZOLAZINYL)BENZENESULPHONAMIDE AND PYRIDINESULPHANAMIDE COMPUNDS AND THEIR APPLICATION AS HERBICIDES

摘要

The invention relates to N-(trazolzinyl)arylsulphonamide compunds such as 2,6-dimethoxy-N-(8-chlor-5-methoxy[1,2,4] triazol [1,5-c]pyrimidin-yl)benzenesulphonamide, 2-methoxy-4-(trifluoromethyl)-N-5,8-dimethoxy [1,2,4] triazole [1,5-c]-pyrimidin-2-yl)pyridine-3-sulphomamide and 2-methoxy-6-methoxycarbonyl-N-(5,8-dimethoxy [1,2,4] triazol- [1,5-a]-pyridin-2-yl)benzenesulphonamide. The compunds are useful as herbicides and have a general formula. They are produced from adequately substituted 2-amino [1,2,4] triazole [1,5-c] pyrimidine and 2-amino [1,2,4] triazole [1,5-a) pyridine compounds and suitably substituted benzenesulphonyl chloride and pyridine-3-sulphonylchloride compounds. 16 claims
