摘要 开发了一种铜催化偶联反应的新方法,涉及以CuCl2·H2O为催化剂,1-(4-羟基-3-甲氧基亚苄基)氨基硫脲(L1)为配体,咪唑与芳基卤反应。新配体L1与铜(II)的配合物首次表现出比铜(I)更好的催化效果。由于铜 (II) 的稳定性和经济性,该方法将是制备 N-芳基咪唑的一种有前途的方法。图形概要
Abstract A new methodology of copper-catalyzed coupling reaction has been developed, involving imidazoles react with aryl halides using CuCl2 · H2O as catalyst and 1-(4-hydroxy-3-me thoxybenzylidene)thiosemicarbazide (L1) as ligand. It is the first time that the complex of newligand L1 and copper(II) presents better catalytic effects than with copper(I). Because of the stability and economy of copper(II)
