SmI2/HMPA converts alkyl iodides and bromides to alkyl samarium reagents which can be cross-coupled with primary alkyl iodides and bromides and secondary iodides in the presence of Cu(I) halides or Li2CuCl4 at room temperature. The alkylation of primary iodides gives good yields of cross-coupling products with negligible home-coupling produces. The method is especially useful for the small scale cross-coupling reactions.
