HERBICIDAL COMPOSITIONS

The present invention provides compositions comprising herbicidally active compounds (A) and (B), where (A) represents one or more compounds of the general formula (I) or agrochemically compatible salts thereof [component (A)], and (B) represents one or more herbicides [component (B)]. The application further relates to a method and to the use of the herbicidal composition according to the invention for controlling harmful plants or for regulating growth.

Preparation method of diclosulam

The invention provides a preparation method of diclosulam and belongs to the technical field of chemical synthesis. The preparation method comprises the following steps: taking 2,2'-dithio-bis(5-ethyoxyl-7-fluoro[1,2,4]triazole[1,5]pyrimidine) as a raw material, and dropwise adding sulfonyl chloride in the presence of sodium nitrate for carrying out chlorosulfonylation to obtain 2-chlorosulfonyl-5-ethyoxyl-7-fluoro[1,2,4]triazole[1,5]pyrimidine; and carrying out sulfonylation on the 2-chlorosulfonyl-5-ethyoxyl-7-fluoro[1,2,4]triazole[1,5]pyrimidine and 2,6-dichloroaniline in the presence of a catalyst DMAP, so that the diclosulam is obtained. The preparation method provided by the invention has the advantages that the yield and quality are basically consistent with the traditional technology when the diclosulam is obtained by adopting the technology, the problems that usage amount of a highly toxic product chlorine is large and potential safety hazards exist in the traditional technology are solved, the total molar yield reaches more than 80%, and the diclosulam is applicable to industrial production application.

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.
