(2) with 1,4-naphthoquinone (3) to give N-aryl-2-amino-1,4-naphthoquinones (1) was found to be catalyzed by copper(II) acetate. In the absence of the catalyst, the reactions are slower and give lower yields with the formation of many colateral products. In the presence of 10 mol % hydrated copper(II) acetate, the reactions are generally more efficient in that they are cleaner, higher yielding, and faster
发现苯胺(2)与1,4-萘醌(3)的氧化加成以产生N-芳基-2-氨基-1,4-萘醌(1)被乙酸铜(II)催化。在没有催化剂的情况下,反应变慢并且由于形成许多副产物而给出较低的收率。在10mol%的水合乙酸铜(II)的存在下,反应通常更有效,因为它们更清洁,产率更高并且更快。
