摘要

Samarium (II) triflate was readily prepared by the reaction of samarium (III) triflate with sec- butyllithium at room temperature in THF. Its reducing ability was examined by pinacol coupling of carbonyl compounds. Sm (OTf) 2 mediated Grignard-type reaction in THF-HMPA effectively; alkylation and allylation of ketones or aldehydes by simple alkyl, allyl, and benzyl halides proceeded via organosamarium intermediates.
