Ru complexes with tridentate hybrid ligands showed a very strong catalytic activity in water at room temperature for benzylic C-H oxidation. Whereas NHCs with a stronger donor ability stabilize the Ru center; nitrogen ligands with a relatively weaker donor ability release from the Ru center, so that they induce a reaction.
