✦ Synopsis

Diiodosamariura prepared in THP reduces allylic iodides and bromides at 0 or -15 °(7 to give organosamarium compounds which are stable under these conditions. These allylic samarium compounds react with many functionalities including the keto group of keto esters. Benzylic samarium compounds were prepared similarly from benzylic bromides.
