A process for the preparation of functional molecules using the thiol-ene coupling reaction and a process for the preparation of protected functional thiols, specifically thioesters is provided. The methods may be used to make functional polymers and other molecules. The method of making a functionalized polymer using a thiol-ene reaction comprises: providing a functionalized thioester having the following formula:
wherein R is a functional group and COR′ is a protecting group; cleaving the functionalized thioester, forming a functional thiol and an acyl group; providing a polymer having a pendant vinyl group; and reacting the polymer with the functional thiol whereby a functionalized polymer is formed, wherein the functional thiol is not isolated prior to reacting with the polymer.
提供了一种使用硫醇烯烃偶联反应制备功能分子的方法,以及一种制备保护的功能硫醇(特别是硫代酯)的方法。这些方法可用于制备功能性聚合物和其他分子。使用硫醇烯烃反应制备功能化聚合物的方法包括:提供具有以下公式的功能化硫代酯:其中R是功能基团,COR'是保护基团;裂解功能化硫代酯,形成功能硫醇和酰基;提供具有侧链乙烯基的聚合物;将聚合物与功能性硫醇反应,从而形成功能化聚合物,其中在与聚合物反应之前不对功能性硫醇进行分离。
