SmI 2 causes reductive dimerization of allylic or benzylic halides, and chiral halides undergo non-stereospecific reduction. [2]

Web2 Feb 2016 · Samarium (II) iodide (SmI2) is a mild one-electron reducing agent used for various reductive reactions of carbonyl compounds, organic halides, and electron deficient olefins. Additional applications of SmI 2 include pinalol coupling, alkyl-carbonyl coupling, deoxygenation, the Reformatsky reaction, and free-radical mediated cyclization.
