Abstract

Control of 1, 2-versus 1, 4-addition of organometallic reagents to enones remains a long- standing problem. There is still no satisfactory 1, 2-directing agent comparable to the 1, 4- directing effect of copper salts. We report that the presence of just 5 mol% indium (III) chloride can significantly alter the amount of 1, 2-product formed in these reactions.
