Nickel-Catalyzed Cycloadditions of Thiophthalic Anhydrides with Alkynes

[摘要]：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.
