被撤回的出版物: An immobilised Co(II) and Ni(II) Schiff base magnetic nanocatalyst via a click reaction: a greener approach for alcohol oxidation (Retracted article. See vol. 46, pg. 9488, 2022)

A Schiff base immobilised nanocatalyst was synthesized via copper catalysed alkyne azide cycloaddition (CuAAC) on a magnetic support. The nanocatalyst exhibited high accessible active sites with a surface area of 76 m(2) g(-1) for a cobalt complex and 57 m(2) g(-1) for a nickel complex. A strong interaction between the magnetic support and the Schiff base was achieved by avoiding leaching during the course of reaction. The nanocatalyst efficiently oxidised both primary and secondary alcohols to carbonyl with improved yield in a solventless system rendering a greener approach.
