Diiodosamarium prepared in tetrahydropyran reduces allylic, benzylic and alkyl halides at 0 or -15 degrees C to give organosamariums which are stable under these conditions. The reactivity of these organometallics has been explored, showing that they are very selective reagents. (C) 1998 Elsevier Science S.A. All rights reserved.
