converted to trifluoromethylated indoles by the tin-radical promoted homolysis of the carbon–iodine bond followed by intramolecular cyclization. The photolysis of trifluoroacetimidoyl iodides enabled both intra- and intermolecular cyclization to indoles and quinolines. Likewise, thermal reactions of N-(2,2,2-trifluoro-1-tritylazoethylidene)anilines provided trifluoromethylated quinolines and indoles
N-Aryltrifluoroacetimidoyl 自由基已通过三种不同的方法产生:锡自由基促进的亚氨基碘化物的脱碘和光化学均分解以及亚氨基偶氮化合物的热均分解。N-[2-(1-炔基)苯基]三氟乙酰亚胺基碘化物已通过锡自由基促进的碳-碘键均裂和分子内环化转化为三氟甲基化吲哚。三氟乙酰亚胺酰碘的光解使分子内和分子间环化成吲哚和喹啉。同样,N-(2,2,2-三氟-1-三苯甲基亚乙基)苯胺的热反应提供了三氟甲基化的喹啉和吲哚。
