Abstract
Samarium (I1) species can be efficiently generated in situ from a reaction between elemental samarium and chlorotrimethylsilane (Me3SiCl)/sodium iodide (NaI) reagent or bromotrimethylsilane (MeaSiBr) in acetonitrile. The reductive coupling reaction of carbonyl compounds was achieved by the action of Sm (I1) reagent thus generated from Sm/Me3SiCVNaI or SdMe3SiBr to give the corresponding pinacol products in moderate to ...
