C—H Oxygenation and N-Trifluoroacylation of Arylamines under Metal-Free Conditions: A Convenient Approach to 2-Aminophenols and N-Trifluoroacyl-ortho-aminophenols.

Direct ortho-hydroxylation through C-H oxygenation and N-trifluoroacylation of anilines was achieved in a single step under metal-free conditions by using a combination of TFA and oxone. The method allowed the formation of functionalised amino phenolic compounds such as ortho-hydroxy-N-trifluoroacetanilides in good yields with broad substrate scope.
