Ruthenium carbene complexes featuring the bulky tridentate N,N′-bis(2,6-diisopropylphenyl)-2,6-pyridinedicarboxamido pincer-type ligand and different stabilizing phosphine ligands were synthesized and characterized. Preliminary results for the application to ring-closing metathesis show low activity for the cyclization of 1,7-octadiene with benzylidene(triphenylphosphine)[N,N′-bis(2,6-diisopropylphenyl)-2, 6-pyridinedicarboxamido-κ3O,N,O/O,N,N]ruthenium(II) (4a,b). Benzylidene(tricyclohexylphosphine)[N,N′-bis(2,6-diisopropylphenyl) -2,6-pyridinedicarboxamido-κ33O,N,O]ruthenmm(II) (5) successfully transformed 1,7-octadiene to cyclohexene and ethylene in good yields at room temperature or 80°C.
