In a cross coupling reaction, in a case where a halogen atom is selected as the leaving group of the raw material compound, a harmful halogen waste forms as a by-product after the reaction, and disposal of the waste liquid is complicated and environmental burden is high. In a carbon-hydrogen activation cross coupling reaction which requires no halogen atom as the leaving group, although no halogen waste forms as a by-product, the reaction substrate is considerably restricted, and the reaction remains a limited molecular construction method.
A method for producing an aromatic compound, which comprises subjecting an aromatic nitro compound and a boronic acid compound to a cross coupling reaction in the presence of a metal catalyst, is hereby provided.
在交叉偶联反应中,如果选择卤素原子作为原料化合物的离去基团,反应后会产生有害的卤素废液作为副产物,废液的处理过程复杂,对环境的负担较重。在不需要卤素原子作为离去基团的碳氢活化交叉偶联反应中,虽然没有卤素废物作为副产物形成,但反应底物受到很大限制,该反应仍然是一种有限的分子构建方法。
本发明提供了一种生产芳香族化合物的方法,该方法包括在金属催化剂存在下,使芳香族硝基化合物和硼酸化合物发生交叉偶联反应。
