perfluorodiacyl peroxides, react selectively with quinone rings of 1,4-naphthoquinones. In the presence of a non-conjugated alkene such as 1-hexene, perfluoroalkyl radicals add to the double bonds of the olefin forming a radical adduct, which selectively adds to the naphthoquinone ring. Several perfluorodiacyl peroxides have been synthesized and used for the direct and alkene-mediated functionalization of naphthoquinones
由全氟二酰过氧化物的热分解产生的全氟烷基自由基与1,4-萘醌的醌环选择性地反应。在非共轭烯烃如1-己烯的存在下,全氟烷基自由基加到烯烃的双键上形成自由基加合物,自由基加合物有选择地加到萘醌环上。已经合成了几种全氟二酰过氧化物,并将其用于萘醌的直接和烯烃介导的官能化。已经通过分子中原子的密度泛函和量子理论计算了所有全氟二酰过氧化物的几何参数和电子密度拓扑,以试图使实验反应性合理化。
