Abstract
A practical Ni(cod)-catalyzed three-component coupling of 1,3-butadiene, carbonyl compounds, and arylboronic acids provides 1,4-disubstituted homoallylic alcohols without any external base and ligand at ambient temperature. The neutral conditions tolerate even highly base-sensitive functional groups.
