Acylcobalt complexes prepared from NaCo(CO)4 and organic halides reacted with butadiene, isoprene and allene to form (acyl-?-allyl)cobalt complexes.Reaction of these with stabilized carbanions resulted in alkylation at the unsubstituted ?-allyl terminus.The procedure provides an overall 1,4-acylation/alkylation of 1,3-dienes in which three carbon-carbon bonds are formed in a one-pot, four-step reaction sequence.
