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.
