Palladium(II)-Catalyzed Norbornene-Mediated Selective meta-C–H Silylation for the Synthesis of Arylsilanes from Primary Benzamides

A palladium(II)-catalyzed norbornene-mediated remote selective meta-C–H silylation of primary benzamides was developed for the synthesis of arylsilanes. Such a conversion provides access to a range of arylsilanes with exclusive selectivity using norbornene (NBE) as the meta-C–H activator. The amide directing group can be detached simultaneously through C–C bond cleavage or undergo a dehydration reaction pathway to form nitriles.
