| Abstract: | A new convenient preparation of samarium dibromide in THF is reported. Pinacol coupling reactions using SmBr2 in catalytic amounts together with mischmetall as a coreductant have been performed with a variety of carbonyl compounds. |
| Keywords: | pinacolic coupling catalysis 1 1 2 2-tetrabromoethane mischmetall samarium dibromide |
