    In: Inorganic Chemistry, 2008, vol. 47, no. 18, p. 8016–8024

    A new set of Ru−Cl complexes containing either the pinene[5,6]bpea ligand (L1) or the C₃ symmetric pinene[4,5]tpmOMe (L2) tridentate ligand in combination with the bidentate (B) 2,2′-bipyridine (bpy) or 1,2-diphenylphosphinoethane (dppe) with general formula [RuCl(L1 or L2)(B)]⁺ have been prepared and thoroughly characterized. In the solid state, X-ray diffraction...

    In: The Journal of Organic Chemistry, 2006, vol. 71, no. 25, p. 9283 -9290

    New polypyridylic chiral ligands, having either C₃ or lower symmetry, have been prepared via a de novo construction of the pyridine nucleus by means of Kröhnke methodology in the key step. The chiral moieties of these ligands originate from the monoterpen chiral pool, namely (-)-α-pinene ((-)-14, (-)-15) and (-)-myrtenal ((-)-9, (-)-10). Extension of the...
