The recent studies of our group on the application of samarium reagent to organic synthesis were reviewed in this paper, which mainly include the following contents: (1) studies on organic reactions promoted by samarium diiodide; (2) the direct use of metallic samarium in organic synthesis; (3) the application of other samarium reagent such as samarium triiodide and organosamarium (allyl samarium bromide) to organic reactions.

Key words: organic synthesis, samarium reagent, samarium diiodide, metallic samarium, samarium triiodide, allyl samarium bromide
