A new visible‐light‐induced trifluoromethylation of isonitrile‐substituted methylenecyclopropanes is developed. A range of substituted 6‐(trifluoromethyl)‐7,8‐dihydrobenzo[k]phenanthridine derivatives are readily furnished by this newly developed tandem reaction with moderate to good yields. This reaction allows the direct formation of two six‐membered rings and three new C−C bonds, including the C−CF3
开发了一种新的可见光诱导的异腈取代的亚甲基环丙烷的三氟甲基化。通过这种新近开发的串联反应,具有中等至良好的收率,可轻松提供一系列取代的6-(三氟甲基)-7,8-二氢苯并[ k ]菲啶衍生物。该反应允许在可见光照射下直接形成两个六元环和三个新的C-C键,包括C-CF 3键。
