Synthesis of fluorinated aroxysulfonyl ureas

Abstract The addition of 2,2,2-trifluoroethylamine (CF 3 CH 2 NH 2 ) in toluene and F -alkylamines (C 6 F 13 (CH 2 ) 2 NH 2 and C 4 F 9 (CH 2 ) 2 NH 2 ) without solvent to aroxysulfonyl isocyanates is a good method for preparing fluorinated aroxysulfonyl ureas. The yield of the reaction is high.
