Abstract

The use of samarium diiodide as a mild and selective reducing agent has become an important tool in organic synthesis. Many reducing agents are reported in the literature. However, due to their low chemoselectivities and various other drawbacks, samarium diiodide has become a useful and readily available reagent. This manuscript provides an update on earlier reviews describing conventional reduction processes of multiple bonds promoted by samarium diiodide. The most recent developments in the use of samarium metal in this field are also discussed. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
