A Barbier-type propargylation of carbonyl compounds with propargyl bromide has been achieved with reactive zinc-copper couple under solvent-free conditions. The reaction of aldehydes with propargyl bromide produced the unique homopropargyl alcohols in excellent yields at room temperature without the formation of homoallenyl alcohols. The ketones reacted with propargyl bromide to give the corresponding homopropargyl alcohols in good to excellent yields at -14 to -16 degrees C. The advantages of this method are excellent yields, short reaction time, high regioselectivity, and avoidance of the use of organic solvents. (C) 2009 Published by Elsevier Ltd.
