FIELD: heterogeneous catalysts. SUBSTANCE: supported homogeneous catalysts that can be used for liquid-phase and gas-phase processes are prepared by pretreating dehydrated NaA zeolite saturated with solution of sodium iodide in mixture of acetone with polar organic solvent followed by adding α,ω-diamine, in particular, polymethylenediamine (n=4-8) or benzidine, and metal complex. Polar organic solvent is selected from methanol, dimethylformamide, Propylene carbonate, and dimethylacetamide. The proposed method enables simultaneous adsorption of precursor and narrowing of zeolite pores, which ensures reliable capture of potential anchoring fragment. EFFECT: higher efficiency. 2 cl, 3 ex
