Get PDFA zinc-catalyzed combined C[BOND]X and C[BOND]H borylation of aryl halides using B2pin2 (pin=OCMe2CMe2O) to produce the corresponding 1,2-diborylarenes under mild conditions was developed. Catalytic C[BOND]H bond activation occurs ortho to the halide groups if such a site is available or meta to the halide if the ortho position is already substituted. This method thus represents a novel use of a group XII catalyst for C[BOND]H borylation. This transformation does not proceed via a free aryne intermediate, but a radical process seems to be involved
