2‐Bromobenzaldehydes are condensed and cyclized with arylhydrazines (or their hydrochlorides) in PEG‐400 at 110 °C in the presence of a catalytic amount of a copper(I) salt along with a base to give 1‐aryl‐1H‐indazoles in high yields. Copyright © 2013 John Wiley & Sons, Ltd.
将2-溴苯甲醛在催化量的铜(I)盐和碱存在下于110°C下与芳肼(或其盐酸盐)缩合并与PEG-400环合,得到1-芳基-1 H吲唑高产。版权所有©2013 John Wiley&Sons,Ltd.
