Abstract
A new method for generation of the samarium (II) species by the reacti on of samarium metal with diethylaluminium iodide (Et2AlI) under mild conditions has been developed. Divalent samarium species generated in situ from a Sm/Et2AlI system caused the reductive coupling of aromatic ketones with moderate stereoselectivity to afford corresponding dl-vi c-diols in moderate yields.
