A new catalytic synthesis of substituted cyclopentenones from alkynes, alkenes bearing an electron-withdrawing group and CO in the presence of Co2(CO)8 is reported. It consists of a coupled process involving Pauson-Khand and Michael-type reactions. The formation of cyclopentenone derivatives is strongly dependent on the nature of the alkyne and of the activated alkene.
