Abstract
4-Fluoride benzenesulfonamide( 2a) and 4-trifluoromethyl benzenesulfonamide( 2n) were synthesized by ammonifination from corresponding benzenesulfonyl chloride. A series of substituted phenylisocyanates( 4a ~ 4m,4t,4Ⅰ) were obtained by reaction of substituted anilines with triphosgene. Finally,twenty-seven novel N-substituted phenyl-4-fluoride( or trifluoromethyl) benzenesulfonylureas were synthesized by condensation of 2 with 4,respectively. The structures were characterized by1 H NMR,IR and ESI-MS.
