Dimethyl sulfoxide and a variety of other highly polar solvents are shown to promote both inter- and intramolecular cyclopentenone formation from alkenes and (alkyne)hexacarbonyldicobalt complexes. Their use leads to significant changes in both regio- and stereoselectivity when compared to other reaction conditions.
