Abstract
A process for preparing functional group-containing olefinic compounds comprises the steps of (a) reacting at least one alkylidene phosphorane with at least one carbonyl-containing compound that comprises at least one group that is a leaving group, or that is capable of subsequent conversion to a leaving group, to form an olefinic compound that comprises at least one leaving group, the carbonyl-containing compound being selected from the group consisting of ketones and aldehydes; and (b) reacting the olefinic compound with at least one functional group-containing nucleophile to form a functional group-containing olefinic compound.
