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.
制备了N-芳基磺酰亚胺化合物,如S,S-二甲基-N-(2,6-二氯苯基)磺酰亚胺,并发现它们能催化芳基磺酰氯化合物(如2-氯磺酰基-7-氟-5-乙氧基[1,2,4]三唑[1,5-c]嘧啶)与芳基胺化合物(如2,6-二氯苯胺)反应,形成N-芳基芳基磺酰胺化合物,如N-(2,6-二氯苯基)-7-氟-5-乙氧基[1,2,4]三唑[1,5-c]嘧啶-2-磺酰胺。通常选择N-芳基磺酰亚胺催化剂的芳基部分和芳基胺化合物的芳基部分是相同的。
