Under solvent-free conditions, it was found that zinc-copper couple could efficiently mediate the Barbier-type reaction of ketones and allyl bromide to give the corresponding homoallylic alcohols in high to excellent yields at room temperature.

A novel and highly efficient synthesis of homoallylic alcohols is achieved by the allylation of carbonyl compounds using magnesium powder as mediator under solvent-free conditions. A series of aldehydes and ketones are converted to the corresponding homoallylic alcohols, the yields of the reaction is considerably high (85-98%). The procedure is environment benign, operationally simple and easy to scale up at room temperature. (C) 2011 Elsevier Ltd. All rights reserved.
