Photochemical Transformations of Quaternary Ammonium Tetrachlorocuprates on an Aerosil Surface

EPR measurements show that the products of photolysis of quaternary ammonium tetrachlorocuprates with 405-nm light in a solvent frozen at 77 K and on an aerosil surface are identical. As compared to matrix isolation at low temperature, immobilization on an aerosil surface makes it possible to extend the temperature range of existence of copper(II) organic products of photolysis by at least 50 K.
