Abstract: A series of novel molecularly imprinted catalysts was prepared by suspension polymerization of acrylonitrile. N-vinylpyridine and divinylbenzene in the presence of Cu(II) ions and various templates: acetophenone, dibenzoylmethane, 4-methoxybenzyl alcohol or 4-hydroxyacetophenone. To improve the catalytic properties, the catalysts were additionally modified inside the active centres by indirect aminolysis of nitrile groups using ethylenediamine and thiourea/ethyl iodide. The catalytic activity of initial samples as well as the modified ones was tested in the model oxidation of hydroquinone to p-benzoquinone using hydrogen peroxide. The catalysts prepared with Cu(II) ions and 4-methoxybenzyl alcohol as the template exhibit the highest activity. In spite of low modification degree, catalysts with guanidyl ligands inside the active centres show higher reaction yield and selectivity than unmodified samples
