Cyclodimerization of α,β-unsaturated ketones catalyzed by lanthanoid tri-2-propoxides

Article abstract of DOI:10.1246/cl.1996.1041

α,β-unsaturated ketones are cyclodimerized by the catalysis of lanthanoid tri-2-propoxides into substituted cycohexanones in good yields. The catalytic activity of the lanthanoids is fairly superior to those of the sodium or aluminum propoxides.
