Influence of Solvents or Additives on the Organic Chemistry Mediated by Diiodosamarium

Part of the Topics in Organometallic Chemistry book series (TOPORGAN, volume 2)

Abstract

The reactivity of diiodosamarium in solvents other than THF or in mixtures of solvents are discussed. The influence of additives able to coordinate to samarium are then considered (amides, amines or ethers). Proton donors sometimes drastically modify the selectivity of reactions induced by diiodosamarium; some metal salts [such as Fe(III) or Ni(II)] in catalytic amounts may also strongly accelerate or modify reactions induced by diiodosamarium. Thanks to the above tuning of the diiodosamarium reactivity, rich and diversified organic transformations have been performed, some examples of which are presented.
