Cyclooctatetraenide derivatives of divalent samarium

Owing to the lack of suitable precursor complexes and applicable synthetic methodology, few soluble divalent organosamarium compounds are known.Recently, a facile route to SmI2(THF)2 proceeding from the bulk metal powder and several organic halides has been described by Kagan and co-workers.We demonstrate herein that this material or the desolvated salt can be used directly in metathetical syntheses (as illustrated by the synthesis of insoluble Sm(C8H8) and the THF-soluble K2Sm(C8H8)2).
