A catalyst contg. metal ions of variable valence used for various chem. reactions, such as polymn. or oxidn., consisted of a solid oxide with surface OH groups, such as silica gel, satd. with a soln. of a polyvalent metal π-alkenyl compd. of a general formula AnMXm, where M = metal ion of variable valence; X = anion; A = alkenyl group; n ≥1; m ≥0. To obtain a catalyst with uniform distribution of metal ions on the carrier surface, the catalyst was oxidized with O or with air (after satn. with a soln. contg. alkenyl compd.) at 20-80°, preferably at 200-500°.
