Abstract

Abstract The Lewis acid-promoted addition of allyl (cyclopentadienyl) iron (II) dicarbonyl (1) to unactivated ketones provides zwitterionic iron-olefin complexes 5 as isolable salts. Treatment of these complexes with NaI in wet acetone affords homoallylic alcohols in good to excellent overall yields.
