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.
