These are N-arylsulfilimine compounds, such as S, S-dimethyl-N- (2,6-dichlorophenyl) sulfilimine, of general formula that catalyzed the reaction of aromatic chloron sulfonyl compounds, such as 2-chlorosulfonyl-7- fluoro-5-ethoxy (1,2,4) -tri azolo (1,5-c) pyrimidine, with aromatic amine compounds, such as 2,6-dichloroaniline, to form N-arylarylsulfonamide compounds (1,2,4 ) triazolo (1,5-c) pyrimidine-2-sulfonamide. The aryl group of the N-arylsulfilimine catalyst and aryl half of the aromatic amine compound in most cases were chosen to be identical. |
