Spiro-fluorene-indenoindenyl-Ir(<scp>i</scp>) complex-catalyzed, 1,3-azole-directed C(sp<sup>3</sup>)–H borylation with pinacolborane
Basic 1,3-azole-directed C(sp<sup>3</sup>)-H borylation is challenging due to potential catalyst deactivation and the CN bond reduction with pinacolborane (HBpin) generated during borylation with B<sub>2</sub>(pin)<sub>2</sub>. This transformation has now been shown to proceed at near-room temperature using a spiro-fluorene-indenoindenyl-Ir(I) catalyst and HBpin without the CN bond reduction.
