A ruthenium‐catalyzed ortho‐alkenylation of acylgermanes with electron‐deficient alkenes through direct C–H bond activation has been developed. With acylgermane as the directing group, this method provides a straightforward access to diverse acylgermanes derivatives with good functional group tolerance and site‐selectivity under mild reaction conditions.

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.
