N-([1,2,4]triazoloazinyl)benzenesulfonamide and pyridinesulfonamide compounds and their use as herbicides

摘要

N-(Triazoloazinyl)arylsulfonamide compounds, such as 2,6-dimethoxy-N-(8-chloro-5-methoxy[1,2,4]-triazolo[1,5-c]pyrimidin-2-yl)benzenesulfonamide, 2-methoxy-4-(trifluoromethyl)-N-(5,8-dimethoxy[1,2,4]-triazolo[1,5-c]pyrimidin-2-yl)pyridine-3-sulfonamide, and 2-methoxy-6-methoxycarbonyl-N-(5,8-dimethoxy[1,2,4]triazolo[1,5-a]pyridin-2-yl)benzenesulfonamide were prepared from appropriately substituted 2-amino[1,2,4]triazolo-[1,5-c]pyrimidine and 2-amino[1,2,4]triazolo[1,5-a]-pyridine compounds and appropriately substituted benzenesulfonyl chloride and pyridine-3-sulfonyl chloride compounds. The compounds were found to be useful as herbicides.
