We have developed a catalyst in which an Ir complex and tertiary amine organic functionalities are coimmobilized on the silica surface. The catalytic activity for aromatic C-H borylation was significantly affected by (i) the linker length of the Ir-bipyridine complex, (ii) the coimmobilized organic functionality, and (iii) the substituents on the aromatic substrate compounds The fine-tuned supported catalyst showed higher activity than the homogeneous Ir-bipyridine complex when using a specific substrate such as benzonitrile. We elucidated this property by conducting solid-state NMR, FT-IR, XAFS, and in situ FT-IR anal.
