Nickel-catalyzed cycloadditions have been developed where thiophthalic anhydrides react with alkynes to afford substituted sulfur-containing heterocyclic compounds. Selective formations of thioisocoumarins, benzothiophenes, and thiochromones were accomplished with three different reaction conditions.
镍催化的环加成反应已经被开发出来，其中噻吩二甲酸酐与炔烃反应生成取代的含硫杂环化合物。通过三种不同的反应条件，可以选择性地合成硫代异香豆素、苯并噻吩和硫色酮。
