EnglishAryl iodides have been found to react with alpha,beta-unsaturated ketones in the presence of catalytic amounts of palladium, an excess of formic acid, and triethylamine, giving rise to conjugate addition type products. The electron-withdrawing power of the group attached to the olefinic double bond, the beta substituent to the carbonyl group, and the basic reaction medium appear to affect greatly the conjugate addition/vinylic substitution ratio.
