Intermediate particles in the catalysis of radical reactions of chlorohydrocarbons
2009
Intermediate products of radical reactions of chlorohydrocarbons catalyzed by copper chloride complexes were synthesized by the photolysis of solutions of [(C4H9)3BzN+]2[CuCl4]2− in chlorobenzene and chloroform at the wavelength corresponding to Cl → Cu charge transfer. It was shown by the EPR method that the products of photolysis were alkyl radicals formed by organic fragments of the quaternary ammonium cation and Cu(II) complexes (supposedly organocopper compounds). The total content of paramagnetic centers decreased. The mechanisms of photoreduction of quaternary ammonium tetrachlorocuprates and possible reasons for the decay of paramagnetic particles were considered.
