Abstract

Abstract The reaction of but-1-en-3-yne derivatives with carbon monoxide and hydrogen in the presence of Rh 4 (CO) 12 catalyst gave formyl-dienes, cyclopentenones and unsaturated lactones, which shows the C= C is much more reactive than the C= C moiety and may provide a new method for the catalytic synthesis of cyclopentenones.
