Aryl boronic esters are bench-stable, platform building-blocks that can be accessed through metal-catalyzed aryl C(sp2)-H borylation reactions. C(sp2)-H bond functionalization reactions using rare- and precious-metal catalysts are well established, and while examples using Earth-abundant alternatives have emerged, Mn catalysis remains lacking. The Mn-catalyzed C-H borylation of furan and thiophene derivatives is reported alongside an in situ activation method providing facile access to the active Mn hydride species. Mechanistic studies showed that blue light irradiation directly affected catalysis by action at the metal center, that C(sp2)-H bond borylation occurs through a C-H metalation pathway, and that the reversible coordination of pinacolborane to the catalyst gave a Mn borohydride complex, which was as an off-cycle resting state.
