solution at room temperature, metallic samarium promoted reductive dimerization cyclization of gem-diactivated alkenes, reductive debromination of vic-dibromides, and reduction of sodium alkyl thiosulfates occur to afford corresponding functionalized cyclopentenes, (E)-alkenes, and disulfides, respectively in good yield. Only sub-stoichiometric quantities of samarium are employed in the former reactions
