Breaking the donor limits : The remarkable coordination chemistry of ECHE (E=Si, Ge) ligands with Group 9 metals (Ir, Rh) and their application in catalytic CH borylation of arenes was investigated. The spectroscopic and structural features of the first [ECE] iridium complexes show the stronger σ‐donating properties of the divalent Si and Ge pincer ligands compared to analogous P III ‐based ligands.
