A highly regioselectiveruthenium-catalyzed ortho-arylation of substituted N-alkyl benzamides with aromatic boronic acids in the presence of [RuCl2(p-cymene)}2], AgSbF6, and Ag2O is described. Further, ortho-arylated N-alkyl benzamides were converted into fluorenones in the presence of trifluoroacetic anhydride and HCl.
