Metal-free chemoselective ortho -C(sp2)-F bond hydroxylation and N-trifluoroacylation of fluoroarylamines for domino synthesis of 2-(N-trifluoroacyl)aminophenols

Abstract A novel chemoselective reaction for the formation of C-O bonds by C(sp2)-F bond cleavage and concomitant N-trifluoroacylation of fluoroanilines using trifluoroacetic acid and Oxone is presented. This domino reaction gives o-hydroxy-N-trifluoroacetanilides in good yields under metal-free conditions in a single step. Selective ortho-directed monohydroxylation and N-trifluoroacylation of 2- and 6-fluoro- or 2,6-difluoro-substituted anilines takes place in this transformation.

Direct C-N bond cleavage of N-vinyl or N-allyl arylamines: A metal-free strategy for N-devinylation and N-deallylation

A simple and convenient N-devinylation and N-deallylation strategy for N-vinyl and N-allyl arylamines in the presence of TFA/oxone is presented with the formation of selective ortho-hydroxylated and N-trifluoroacylated arylamine product in good yields. Th

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.
