C−H Activation Based Copper‐Catalyzed One‐Shot Synthesis of N,O‐Bidentate Organic Difluoroboron Complexes

Organic BF2 complexes exhibit characteristics such as large Stokes shift, high quantum yield, strong emission intensity, and robust chemical stability, thereby being extensively used in various applications. Herein, we disclose a novel copper-catalyzed cascade C-H activation/acyloxylation and difluoroboronation of 2-phenylpyridine derivatives, thus providing a straightforward and rapid gateway to a series of N,O-bidentate organic BF2 complexes...
