Metal-organic layers stabilize earth-abundant metal-terpyridine diradical complexes for catalytic C-H activation.

ABSTRACT: We report the synthesis of a terpyridine-based metal-organic layer (TPY-MOL) and its metalation with CoCl₂ and FeBr₂ to afford CoCl₂·TPY-MOL and FeBr₂·TPY-MOL, respectively. Upon activation with NaEt₃BH, CoCl₂·TPY-MOL catalyzed benzylic C-H borylation of methylarenes whereas FeBr₂·TPY-MOL catalyzed intramolecular C_sp³ -H amination of alkyl azides to afford pyrrolidines and piperidines. X-ray absorption near edge structure (XANES), extended X-ray absorption fine structure (EXAFS), X-ray photoelectron spectroscopy, UV-Vis-NIR spectroscopy, and electron paramagnetic spectroscopy (EPR) measurements as well as density functional theory (DFT) calculations identified M(THF)₂·TPY-MOL (M =
