Palladium‐Catalyzed Borylation of Sterically Demanding Aryl Halides with a Silica‐Supported Compact Phosphane Ligand

Immobile but active: A silica-supported “compact” phosphane, Silica-SMAP, can be used in the Pd-catalyzed borylation of aryl chlorides or bromides with bis(pinacolato)diboron (see scheme). The Silica-SMAP/Pd system significantly expands the substrate scope of the borylation toward sterically and electronically challenging aryl halides.
