Reactions of alkyl halides (R1X) with acyltriphenylgermanes (R2COGePh3) under radical conditions provide mixtures of ketones (R1COR2), diketones (R2COCOR2), alkanes (R1H) and alkenes. These products arise from radical-radical reactions, and the results suggest that bimolecular addition reactions of alkyl radicals to acylgermanes are too slow to propagate radical chains.
Photochemical primary processes of benzoyltriphenylgermane and benzoylphenyldimethylgermane were studied at room temperature in cyclohexane and chloroform. The germyl radicals generated were observed directly with the aid of a laser-photolysis technique.
