文摘

The ester-directed regioselective borylation of arenes catalyzed by a silica-supported monophosphine−Ir complex displayed a significantly broad substrate scope toward heteroaromatic compounds, including thiophene, pyrrole, furan, benzothiophene, benzofuran, indole, and carbazole derivatives. The regioselectivity is complementary to the selectivities observed in the heteroarene C−H borylation with the dtbpy-Ir catalyst system.
