A radical approach toward 6‐perfluoroalkylphenanthridines employs the Togni reagent or derivatives thereof as radical precursors and occurs in the absence of a transition metal. Bu4NI is applied as radical initiator and phenanthridines are formed in good to excellent yields. In contrast to the currently intensively investigated trifluoromethylation of arenes, the arene core is formed during the trifluoromethylation
对6-全氟烷基菲啶的自由基方法采用Togni试剂或其衍生物作为自由基前体,并且在不存在过渡金属的情况下发生。将Bu 4 NI用作自由基引发剂,并以良好至极好的收率形成菲啶。与目前深入研究的芳烃三氟甲基化相反,在这种方法中,芳烃核是在三氟甲基化过程中形成的。
