Usage

Description

Flumetsulam is a highly active herbicide belonging to the triazolopyrimidine sulfonanilide class. It possesses the ability to inhibit acetolactate synthase, which is crucial for the growth and development of broadleaf weeds.
Used in Agricultural Industry:
Flumetsulam is used as a herbicide for controlling broadleaf weed species. It offers selectivity to several major agronomic crops, making it suitable for both soil and foliar applications. This ensures effective weed management without causing significant harm to the desired crops, thus promoting healthy crop growth and increased agricultural productivity.

N-ARYLSULFILIMINE COMPOUNDS AND THEIR USE AS CATALYSTS IN THE PREPARATION OF N-ARYLARYLSULFONAMIDE COMPOUNDS

N-arylsulfilimine compounds, such as S,S-dimethyl-N-(2,6-dichlorophenyl)sulfilimine, were prepared and found to catalyze the reaction of aromatic sulfonyl chloride compounds, such as 2-chlorosulfonyl-7-fluoro-5-ethoxy[1,2,4]triazolo[1,5-c]pyrimidine, with aromatic amine compounds, such as 2,6-dichloroaniline, to form N-arylarylsulfonamide compounds, such as N-(2,6-dichlorophenyl)-7-fluoro-5-ethoxy[1,2,4]triazolo[1,5-c]-pyrimidine-2-sulfonamide. The aryl moiety of the N-arylsulfilimine catalyst and the aryl moiety of the aromatic amine compound were generally chosen to be identical.

Aqueous process for the preparation of 5-methyl-n-(aryl)-1,2,4-triazolo(1,5-A)pyrimidine-2-sulfonamides

5-Methyl-N-(aryl)-1,2,4-triazolo[1,5-a]-pyrimidine-2-sulfonamides are prepared by the cyclization of N -(3-(((aryl)amino)sulfonyl)-1H-1,2,4-triazol-5-yl)amines with 4-methoxy-3-butene-2-one or its synthetic equivalents in the presence of an aqueous base. By controlling the pH of the condensation between 8.5 and 10.5, by-product formation can be substantially reduced.

Substituted 1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamides, compositions containing them, and their utility as herbicides

Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonamides, e.g., 5,7-dimethyl-N-(2,6-dichlorophenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide and their agriculturally acceptable salts are prepared. These compounds and compositions containing them are useful for the control of unwanted vegetation. Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonyl chlorides and substituted anilines and their use as intermediates are also described.
