4-triazol-3-yl)thio]pentane-2,4-dione afforded 1-(6-methylthiazolo[3,2-b][1,2,4]-triazol-5-yl)ethan-1-one, the reactions of which with hydroxylamine, hydrazincarboxamide, hydrazincarbothioamide, hydrazine hydrate and para-toluenesulfonyl hydrazide resulted in the formation of the corresponding derivatives. 1-(6-Methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethan-1-one oxime reacted with alkyl halides and phenyl
Herbicidal triazolecarboxamides are useful as agricultural chemicals. In particular the compounds are useful as herbicides, both general and selective, both post-emergent and pre-emergent. Examples of selective activity include excellent control of blackgrass and wild oats with outstanding wheat tolerance, and control of crabgrass, giant foxtail, barnyardgrass and blackgrass with outstanding tolerance to corn, soybeans, rice, cotton, wheat, sugarbeets and rape.
