A metal-free method (KOH/DMSO) for the synthesis of o-halodiarylamines from o-halophenols and 2-bromo-N-arylpropanamide via Smiles rearrangement reaction as a key step has been developed in this paper. This method has advantages of simple and efficient operation, easy available starting materials and transition-metal-free conditions. It exhibits the certain application value. Using this method, a series of o-halodiarylamines have been synthesized in 23%~81% yields.

Key words: transition-metal-free reaction, o-halophenols, o-halodiarylamines, Smiles rearrangement reaction
