Regioselective, hydrogen‐acceptor‐free CH bond silylation of anisoles or alkoxy‐substituted benzenes with hydrosilanes was achieved by use of a half‐sandwich scandium catalyst. The reaction proceeds through ortho‐CH activation of an anisole compound by a scandium hydride species followed by the silylation of the resulting scandium 2‐anisyl species with a hydrosilane (see scheme).
