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.
N-芳基磺酰亚胺化合物,例如S,S-二甲基-N-(2,6-二氯苯基)磺酰亚胺,已被制备并发现可催化芳香磺酰氯化合物,例如2-氯磺酰基-7-氟-5-乙氧基[1,2,4]三唑[1,5- c]嘧啶,与芳香胺化合物,例如2,6-二氯苯胺,形成N-芳基芳基磺酰胺化合物,例如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。N-芳基磺酰亚胺催化剂的芳基部分和芳香胺化合物的芳基部分通常被选为相同的。
