The Ï-carbocation reactive species generated by decomposition of 2-(4-azidophenyl)benzothiazoles in trifluoromethanesulfonic acid undergo intermolecular CâC or NâN coupling to afford benzothiazole-substituted 2,2â²-diaminobiphenyls.
2-(4-azidophenyl)benzothiazoles 在三氟甲磺酸中分解产生的 Ï-carbocation 活性物质会发生分子间 CâC 或 NâN 偶联,生成苯并噻唑取代的 2,2â²-二氨基联苯。
