  New ruthenium(II) mixed metallocene derived complexes: Synthesis, characterization by X-ray diffraction and evaluation on DNA interaction by atomic force microscopy

  摘要：

  A new family of Ru(II) mixed metallocene complexes of the type [Ru(eta(5)-C5H5)(eta(6)-arene)][PF6] has been synthesized and fully characterized by NMR and UV-Vis spectroscopy. X-ray analysis of single crystal was achieved for all the complexes and revealed the presence of two enantiomers expected for planar chirality originated by the eta(6) coordination of the arene prochiral ligands. Studies of interaction of the new complexes with pBR322 DNA by atomic force microscopy showed very strong and different types of interaction. Antiproliferative tests were examined on human leukemia cancer cells (HL-60) using the MTT assay, and the IC50 values revealed low antiproliferative activity compared to cisplatin.

  A series of ruthenium(II) complexes with the general formula [Ru(eta(5)-C5H5) (eta(6)-substituted arene)](+) [PF6](-) (substituted arene = 2-phenylpyridine (1), dibenzosuberone (2) and toluene (3)), in combination with isopropyl alcohol were used for the polymerization of epsilon-caprolactone. The polymerization was found to be quantitative and controlled, with PDI in the range 1.1-1.3. By means of MALDI-ToF analyses, functionalization studies with D,L-lactide and NMR monitoring techniques, it has been found that the polymerization proceeds via a living Activated Monomer mechanism (AM) involving an eta(6)-eta(4) change of the coordination mode of the arene. These experimental results were corroborated by DFT studies. The growth of several polymer chains per ruthenium atom highlights interesting potentialities for molecular weight control and catalyst economy. The stability of the ruthenium complexes allows their recovery at the end of the polymerization, which can be viewed as a further advance in a green chemistry frame. (C) 2011 Elsevier B.V.
