摘　　要：方便地制备了复合物 Fe(NO3) 3.1 .5 N2 O4 和 Cu(NO3) 2 .N2 O4 ,与金属的硝酸盐相比 ,该复合物可对酚类化合物进行选择性单硝化或二硝化作用 ,从实验结果分析 ,复合物对硝化反应的速率和收率具有协同效应 。The complex compounds of Fe(NO 3) 3·1.5N 2O 4 and Cu(NO 3) 2·N 2O 4 were easily prepared for the efficient and selective mono & dinitration of phenolic compounds. In comparison with metal nitrate, these complexes resemble a synergetic effect on the rates and the yields of the reactions. High ratio of p nitrophenol formation vs o nitrophenol was also observed in the mononitration reactions.
