摘要 在无过渡金属催化剂和无配体存在下,KOH/DMSO超强碱能够促进Sonogashira偶联反应。碱的类型、溶剂对Sonogashira反应的影响,以及底物的范围做了考察。研究结果表明:在没有钯或铜和配体形成的催化剂、也没有相转移试剂存在下,在比较温和的反应条件下,强碱就可以促进Sonogashira反应。 Without transition metal catalysts and ligands, KOH/DMSO super base can promote Sonogashira cross coupling reaction. The effect of bases, solvents on Sonogashira reaction, and the scope of substrates are examined in this paper. The results demonstrated that transition metal-free, ligand-free Sonogashira reaction under mild conditions can give good results.
