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: ##STR1## 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.
这项发明提供了生产表现非线性光学响应的新型
酯类的多步骤过程实施方案。其中一个过程实施方案是通过Schiff碱与取代
乙酸反应形成
苯乙烯醇中间体:##STR1## 然后将
苯乙烯醇中间体脱羧,再在
吡啶类催化剂存在下酯化,以提供具有共轭结构的
酯类。
