Experimental and Theoretical Investigation of the Mechanism of the Reduction of O from Air to O by VO-,,-Amidate Compounds and Their Potential Use in Fuel Cells.

The two-electron reductive activation of O to O is of particular interest to the scientific community mainly due to the use of peroxides as green oxidants and in powerful fuel cells. Despite of the great importance of vanadium(IV) species to activate the two-electron reductive activation of O, the mechanism is still unclear. Reaction of VO species with the tridentate-planar carboxamide (ΗL) ligands in solution (CHOH:HO) under atmospheric O, at room temperature, resulted in the quick formation of [V(═O)(η-O)(κ-L)(HO)] and -[V(═O)(κ-L)] compounds.

Gaining Insights on the Interactions of a Class of Decorated (2-([2,2'-Bipyridin]-6-yl)phenyl)platinum Compounds with c-Myc Oncogene Promoter G-Quadruplex and Other DNA Structures.

Organometallic molecules offer some of the most promising scaffolds for interaction with G-quadruplex nucleic acids. We report the efficient synthesis of a family of organoplatinum(II) complexes, featuring a 2-([2,2'-bipyridin]-6-yl)phenyl tridentate (N N C) ligand, that incorporates peripheral side-chains aiming at enhancing and diversifying its interaction capabilities. These include a di-isopropyl carbamoyl amide, a morpholine ethylenamide, two enantiomeric proline imides and an oxazole.
