Abstract
Irradiation for permethyloligogermanes, Me(Me2Ge)(n)Me (n = 2-5), in C Cl4-CH3CN in the presence of 9,10-dicyanoanthracene (DCA) afforded the corresponding chlorogermanes and hexachloroethane. Fluorescence of DC A was quenched by the oligogermane with a diffusion-controlled rate. A mechanism of free-radical chlorination involving oligogermane cation radicals and a DCA anion radical is proposed for the germanium-germani um cleavage. (C) 1998 Elsevier Science S.A.
