摘要：

In contrast to previous failure to obtain conjugate addition products from the reaction of alkali diphenylmethides to acrylic esters, reaction conditions can be selected to afford adducts even from methyl acrylate. Yields of addition products are increased as alkyl substituents are introduced into the acrylate. Certain highly substituted cinnamates do not undergo conjugate addition but instead undergo carbonyl addition to give low yields of ketones.
