Using β-diketiminate Mg(ii) complexes containing either alkyl, aryl or amide groups, the regioselective functionalization of a wide range of fluoroarenes is accomplished but in uniquely different ways. Overcoming common limitations of traditional s-block bases, kinetically activated [(DippNacnac)Mg(TMP)] (1) deprotonates these molecules at room temperature, trapping sensitive fluoroaryl anions that can then engage in Negishi cross-coupling; whereas [(DippNacnac)Mg(R)THF] (R = nBu, Ph, benzofuryl) have proved to be effective reagents for C-F bond alkylation/arylation via pyridine directed C-F bond cleavage.

Cross-coupling reaction of polyfluoroarenes with Grignard reagents via pyridine-directed cleavage of C-F bond in the absence of metal catalysts was developed. A possible mechanism was suggested.
