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
的反应邻-fluorinated苯胺与化学计量的Ti(NME 2)4在均三甲苯(典型地为23,在120℃1H),得到适度的到相应的高收率Ñ,ñ从defluoroamination所得二甲基-1,2-苯二胺衍生物与起始苯胺的NH 2相邻的氟原子。通常根据确定的区域化学趋势(活化和失活),反应性随附加的环氟化作用而增加。
