Photochemical reactions of vinyl-, styryl-, and benzyl-substituted digermanes were investigated by chemical trapping experiments. Photolysis of vinylpentamethyldigermane afforded 1-trimethyl-2-(pentamethyldigermyl)ethane as a major product, and styrylpentamethyldigermanes gave mainly styryltrimethylgermane. On the other hand, photolysis of benzyl-substituted digermanes (benzylpentamethyldigermane and 1,2-dibenzyltetramethyldigermane) gave hydrogermanes and hydrodigermanes as main products, respectively. These products were derived from germyl radicals generated by photoinduced homolysis of the germanium–germanium bond. In carbon tetrachloride (CCl<SUB>4</SUB>), these germyl radicals were converted to the corresponding chlorogermanes by abstraction of a chlorine atom. Germylene species were also to be evolved from such photolyses.
