Cyclic acid anhydrides (succinic and glutaric anhydrides and In these reactions the formation of a samarium keto carboxylate intermediate is likely; as a matter of fact, keto some of their derivatives) undergo fast Barbier-type reactions mediated by samarium diiodide in the presence of catalytic car
