We describe an Ir-catalyzed intramolecular reaction of 2-alkynyl diaryl sulfides, which gives 9-arylidene-9H-thioxanthene derivatives via 6-exo-dig cyclization. When 2-alkynylphenyl naphthyl sulfides are used, divergent synthesis of triaryl-fused thiepines and diaryl-substituted benzothiophenes can be achieved by simply choosing the reaction temperature.
我们描述了 2-炔基二芳基硫化物的 Ir 催化的分子内反应,该反应通过 6- exo - dig环化产生 9-arylidene-9 H-噻吨衍生物。当使用2-炔基苯基萘硫醚时,只需选择反应温度即可实现三芳基稠合硫杂和二芳基取代苯并噻吩的不同合成。
