Cobalt catalysts with electronically enhanced site selectivity have been developed, as evidenced by the high ortho-to-fluorine selectivity observed in the C(sp<sup>2</sup>)-H borylation of fluorinated arenes. Both the air-sensitive cobalt(III) dihydride boryl 4-Me-(<sup>iPr</sup>PNP)Co(H)<sub>2</sub>BPin (1) and the air-stable cobalt(II) bis(pivalate) 4-Me-(<sup>iPr</sup>PNP)Co(O<sub>2</sub>C<sup>t</sup>Bu)<sub>2</sub> (2) compounds were effective and exhibited broad functional group tolerance a ...[more]
