An efficient ruthenium(II)-catalyzed intermolecular selective ortho C-H silylation of 2-aryloxazoles has been described for the first time, which provides a convenient and practical pathway for the synthesis of versatile organosilane compounds with good functional group tolerance and regioselectivity. This catalytic system could be also applied to the dehalogenation of Cl or Br group.
