- Аннотация: The structure and activity of C-Cl bond metathesis catalysts containing CuCl2 and triethylenetetramine (TETA) supported on silica were studied. The catalysts were found to contain similar to 40% Cu(II) as paramagnetic complexes of the composition Cu(TETA)(2)Cl-2 and diamagnetic binuclear or polynuclear copper complexes, which are undetectable by EPR spectroscopy. The catalytic activity of the test systems in the radical reaction of C-Cl bond metathesis in the CCl4-C10H22 system was maximum at a Cu(II) concentration of similar to0.5 wt % on the support. A kinetic scheme was proposed, which suggests that only mononuclear copper complexes participate at the stage of radical generation, whereas termination can also occur on binuclear or polynuclear complexes.
