(2) in the presence of alkyl halides leads to C-centered radicals which can be trappedby alkenes and yields saturated and/or unsaturated addition products. Carbon radicals are generated via halogen abstraction by the initially formed metal-centered radicals resulting from homolysis of the metal-metal bond of dimericmediators 1 and 2. No reaction occurs using octacarbonyldicobalt (3).

diastereofacial selectivity in reactions of a series of alkyl-substituted cyclohexylradicals has been investigated. In additions of cyclohexylradicals to alkenes, it has been found that only substituents bound at the olefinic center being attacked by the radical influence the equatorial-axial selectivity. Substituents bound to the radical center or axial substituents p to the radical center lead to increased
