Reactions of ortho-fluorinated anilines with stoichiometric Ti(NMe2)4 in mesitylene (typically for 23 h at 120 °C) afforded moderate to high yields of the corresponding N,N-dimethyl-1,2-phenylenediamine derivatives resulting from defluoroamination of a fluorine atom vicinal to the NH2 of the starting aniline. Reactivity increases with additional ring fluorination in general accordance with established
