The anodic oxidation of 4-(2′-alkenyfphenyl)phenols in acetonitrile/methanol affords spirodienones arising from cyclization of the olefinic side-chain to the 4-position of the phenol and reaction of the resulting benzylic cation with methanoi. The efficiency of this carbon—carbon bond-forming reaction is dependent upon the olefinic substituents.
在乙腈/甲醇中对4-(2'-链烯基苯基)苯酚进行阳极氧化可提供螺二烯酮,该螺二烯酮是由烯属侧链环化至苯酚的4-位以及所得苄基阳离子与甲烷反应而产生的。形成碳-碳键的反应的效率取决于烯烃取代基。
