Notes: Dysprosium metal promoted Barbier-type allylation of ketones and aldehydes has been investigated. It has been shown that dysprosium metal (activated by mercuric chloride) is effective in promoting the reaction of ketones with allyl iodide. The corresponding homoallylic alcohols are obtained in satisfactory yields. This reaction is regioselective and chemoselective. An α, β-unsaturated ketone affords a 1,2-addition product selectively. Reactive groups (such as Cl, Br, and methoxy) of aromatic ketones remain unchanged under the reaction conditions. © 1998 John Wiley & Sons, Inc. Heteroatom Chem 9:475-478, 1998
