A novel rearrangement reaction based on the structure of N‐fluoro‐N‐(phenylsulfonyl) benzamides (FPSBA) was developed. In the presence of base, unsymmetrical N‐alkyl diaryl ureas were obtained in good yields which were accomplished through secondary alkyl phenylamines initiated 1,2‐phenyl‐shift migration rearrangement of N‐fluoro‐N‐(phenylsulfonyl) benzamides. The reaction was carried out without...
