摘要
报道了一个新颖的方法来制备四取代萘化物,该方法通过NiCl_2催化下的二芳基乙炔与格氏试剂的无配体偶联反应实现.该方法避免了已有方法中的特殊配体和昂贵催化剂的使用.此外,本方法还具有反应条件温和,产率高,底物适用范围广等优点,为多取代萘的制备提供了一个有效的方法.
A novel approach for the synthesis of tetra-substituted naphthalenes is demonstrated through the ligand-free coupling of a wide range of alkynes with Grignard reagents catalyzed by NiCl2, avoiding the use of special ligands and expensive catalysts used in previous methods. Other outstanding features include mild reaction conditions, good yields and wide functional group tolerance. The protocol provides an efficient method for the synthesis of highly substituted naphthalenes.
