With a strategy of the formation of benzynes by using diaryliodonium salts, a cycloaddition reaction of -arylpyrroles with benzynes was reported. A wide range of bridge-ring amines with various substituents have been synthesized in moderate to excellent yields (35-96%). Furthermore, with a catalytic amount of TsOH·HO, these amines can be converted into the corresponding -phenylamine derivatives easily, which are potentially useful in photosensitive dyes.
通过使用二芳基碘鎓盐形成苯炔的策略，报道了芳基吡咯与苯炔的环加成反应。已以中等至优异的产率（35 - 96%）合成了多种带有不同取代基的桥环胺。此外，在催化量的对甲苯磺酸一水合物存在下，这些胺可以轻松转化为相应的芳基苯胺衍生物，它们在光敏染料方面具有潜在用途。
