Compounds of n - ((1,2,4) triazoloazinyl) benzenesulfonamide and pyridinesulfonamide, and their use as herbicides.

The invention relates to compounds of N- (triazoloazinyl) arylsulfonamide, such as 2,6-dimethoxy-N- (8-chloro-5 - methoxy [1, 2, 4] triazolo [1,5 - c] pyrimidine - 2 IL) benzenesulfonamide, 2 METHOXY 4 (TRIFLUOROMETHYL) N (5.8 DI - methoxy [1, 2, 4] triazolo [1,5 - c] pyrimidine 2 yl) -pyridine 3 - sulfonamide, and 2-methoxy-6-methoxycarbonyl-N (5,8 - dimethoxyl [1 , 2, 4] triazolo - [1,5 - a] pyridine-2yl) benzenesulfonamide, PREPARED FROM SUBSTITUTED COMPOUNDS OF 2 PROPER - AMINO [1, 2, 4] triazolo [1,5 - C] pYRIMIDINE COMPOUNDS AND 2 - AMINO [1, 2, 4] triazolo [1,5 - A] pYRIDINE AND suitably substituted compounds BENZENOSULFONIL CHLORIDE AND pYRIDINE CHLORIDE 3 sulfonyl. It has been found that these compounds are useful for application as herbicides.
