Catalytic Activity of Immobilized Transition Metal Complexes with Monoethanolamine in Carbon Tetrachloride Addition to Multiple Bonds

The rates of CCl₄ addition to octene-1 in the presence of monoethanolamine complexes with Mn, Cu, V, Co, and Ni ions immobilized on the surface of silica have been determined. The majority of catalysts exhibit an inverse dependence of relative catalytic activity on surface metal concentration. Changes in the total concentrations and ligand environments of paramagnetic ions in the course of reaction are studied by EPR spectroscopy for copper- and vanadyl-containing catalysts. It has been found that the activity of complexes correlates with the rate of reduction of a metal ion in the course of a catalytic reaction.
