absence of any photocatalyst or additives. This method has allowed for the facile functionalization of pyridones and related N-heteroarenes such as azaindole. This protocol is operationally simple, uses readily available materials, and is tolerable for electron-neutral and -rich functional pyridones. Cyclic voltammetry was utilized as a mechanistic probe, and preliminary data suggest the reaction may
Trifluoromethylation of aromatic and hetero-aromatic compounds by CF3I in the presence of Fe(II) compound, H2O2 and dimethylsulfoxide was investigated. Various trifluoromethylated benzene derivatives, six-membered nitrogen-containing aromaticcompounds and five-membered hetero-aromatic compounds were obtained under mild conditions. General orientation of electrophilic substitution of aromaticcompounds was observed
研究了在Fe(II)化合物,H 2 O 2和二甲基亚砜的存在下,CF 3 I对芳族和杂芳族化合物的三氟甲基化作用。在温和条件下获得了各种三氟甲基化苯衍生物,六元含氮芳族化合物和五元杂芳族化合物。与先前在其他自由基三氟甲基化中报道的类似,观察到芳族化合物的亲电子取代的一般取向。
