Synthesis and structure of nickel and copper complexes containing the N-allyl-o-hydroxyacetophenoniminato ligand and the application of copper complex as catalyst for aerobic alcohol oxidations

Complex [Cu(Lallyl)2] is a selective catalyst, in combination with TEMPO, for the oxidation of benzylic-type alcohols using air at atmospheric pressure and room temperature. The use of ionic liquids as solvents gave good aldehyde yields and allowed catalyst recycling.
