bond lengths of the rutheniumcomplexes. Furthermore, the electronic nature of the azolate moiety modulates the catalytic activity of the rutheniumcomplexes in the hydrogenation of carbondioxide under supercritical conditions and in the transfer hydrogenation of acetophenone. DFT calculations were performed to shed light on the mechanism of the hydrogenation of carbondioxide and to clarify the impact

AbstractWe synthesized substituted pyrazolylpyridine ligands to examine their donor properties by spectroscopic (IR, NMR) and computational (AM 1) methods. The influence of the substitution patterns on spectroscopic and thermodynamic features of molybdenum oxobisperoxo complexes [(L–L)MoO(O2)2] (L–L=2‐(1‐alkyl‐3‐pyrazolyl)pyridine/pyrazine) correlates with the activities of the complexes in catalytic olefin epoxidation reactions. This further proof for the relation between the Lewis acidity and the catalytic activity of epoxidation catalysts supports a reaction mechanism in which the peroxo complex activates the oxidizing agent (H2O2, ROOH) instead of directly transferring an oxygen atom from a π2‐peroxo ligand to the olefin.
