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.
硅胶负载单膦-铱配合物催化的酯导向区域选择性芳基硼酸化反应对杂芳环化合物具有显著广泛的底物范围，包括噻吩、吡咯、呋喃、苯并噻吩、苯并呋喃、吲哚和咔唑衍生物。该区域选择性与 dtbpy-Ir 催化剂体系观察到的杂芳烃 C-H 硼酸化反应的选择性互补。
