CA 2066211

2066211 9103457 PCTABS00003 This invention provides multistep process embodiments for the production of novel esters which exhibit nonlinear optical response. A process embodiment is illustrated by the reaction of a Schiff base with a substituted acetic acid to form a stilbene alcohol intermediate (I). The stilbene alcohol intermediate is decarboxylated, and then is esterified in the presence of a pyridine type catalyst to provide an ester with a conjugated structure.
