Coordinating Activation Strategy-Induced Selective C?H Trifluoromethylation of Anilines
A simple protocol for the synthesis of 2-(trifluoromethyl)aniline derivatives through a coordinating activation strategy was developed. The reaction showed good reactivity and gave the target products in moderate to good yields. Pleasingly, the directing group could be recovered in excellent yield. Furthermore, this strategy allowed efficient access to the synthesis of floctafenine. A single-electron-transfer mechanism was proposed to be responsible for this trifluoromethylation reaction.
