在高氯酸锂/硝基甲烷电解液中，实现了阳极活化的烯氧基苯与烯烃之间的电催化形式[2+2]环加成反应。这些电解底物的烯氧基苯部分在形成能够接受亲核烯烃的自由基阳离子中起着重要作用，然后在中间体的环丁烷和苯醚部分之间进行分子内电子转移。
Electrocatalytic formal [2+2] cycloadditions between anodically activated enyloxy benzene and alkenes have been accomplished in a lithium perchlorate/nitromethane electrolyte solution. The enyloxy benzene moiety of these electrolytic substrates played an important role in the formation of a radical cation that could accept nucleophilic alkenes, followed by intramolecular electron transfer between the cyclobutane and phenyl ether moieties of the intermediates.
