If every cyclohexyl and 1-octyl radical is formed irreversibly and abstracts a hydrogen atom from (CH 3 Si) 3 SiH (Scheme 3), then the ratio k Se /k Br should be equal to the ratio of cyclohexane to oc…

Carbon-centered radicals produced from organocobalt complexes also undergo the characteristic radical reactions of addition and cyclization.
