摘要报道了乙酸铜（II）介导的酚类与4-对甲苯磺酰基香豆素的Ullmann型反应合成4-芳氧基香豆素。该方法具有操作简单、产率适中、无配体乙酸铜（II）作为绿色催化剂等优点。
Abstract A copper(II) acetate mediated Ullmann-type reaction of phenols with 4-tosylcoumarin for the synthesis of 4-aryloxycoumarins is reported. The method has some attractive features such as operational simplicity, moderate to good yields, and the use of ligand-free copper(II) acetate as a green and stable catalyst.
