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.

A number of 2,6-disubstituted and 2,3,6-trisubstituted anilines have been prepared via the selective para dehalogenation of the corresponding anilines. Modification of the substituents on the amino nitrogen demonstrates that the selectivity is derived from steric rather than electronic effects. The effects of the choice of formate hydrogen donor, Pd catalyst, solvent, and temperature upon the efficiency and selectivity of the dehalogenation are discussed.
