Introduction

Samarium triiodide (SmI3) is a yellow powder with a melting point of 820 ˚C, unstable towards air and moisture. It is commercially available and has been widely used in organic reactions, such as elimination, conjugate addition, carbonyl reduction, intramolecular cyclization and nucleophilic substitution reactions. It can also be regarded as an efficient metal catalyst and a Lewis acid catalyst to accelerate reactions and to improve yields for organic transformations. Herein, the applications of SmI3 in recent years are listed and reviewed.
