Abstract
N-(Triazoloazinyl)thiophenesulfonamide compounds were prepared from appropriately substituted 2-amino[1,2,4]triazolo[1,5-c]pyrimidine, 2-amino[1,2,4]triazolo[1,5-a]pyrimidine and 2-amino[1,2,4]triazolo[1,5-a]pyridine compounds and appropriately substituted thiophenesulfonyl chloride compounds. The compounds were found to be useful as herbicides.
