Indoles, including tricyclic derivatives, are produced by cyclisations of aryl radicals onto vinyl halides followed by elimination of halide radical and tautomerism of the resulting product; the aryl radicals are produced using âclean methodologyâ either by reaction of iodide ions with arenediazonium salts or by reaction of phosphorus-centred radicals with aryl iodides.

吲哚,是通过将芳基自由基环化到
乙烯基卤化物上,随后消除卤素自由基以及生成的产物的互变异构作用产生的;这些芳基自由基是通过“清洁方法学”生成的,或者是通过
碘离子与芳二氮鎓盐的反应,或者是通过
磷中心自由基与芳基
碘的反应。
