A simple and practical photochemical strategy for intermolecular perfluoroalkyl-alkenylation of alkenes with 2-amino-1,4-naphthoquinones and perfluoroalkyl iodides has been demonstrated under visible-light irradiation. Mechanistic studies reveal that easily available 2-amino-1,4-naphthoquinone substrates can serve as efficient photosensitizers to activate perfluoroalkyl iodides through a photoredox
在可见光照射下,已经证明了用2-氨基-1,4-萘醌和全氟烷基碘对烯烃进行分子间全氟烷基-烯基化的简单实用的光化学策略。机理研究表明,容易获得的2-氨基-1,4-萘醌底物可作为有效的光敏剂,通过光氧化还原过程活化全氟烷基碘。因此,所开发的自由基中继反应可顺利进行,而无需其他过渡金属和光催化剂。
