Abstract
Some reactions of diiodosamarium are greatly accelerated by addition of catalytic amounts (1%) of various transition metal halides. The most useful catalyst is NiI2. Many Barbier reactions can be performed in a few minutes at room temperature even in the absence of HMPA. The catalyst modifies the reaction profile of SmI2, for example intermolecular reactions of organic halides on esters are very fast giving tertiary alcohols.Keywords
