Pd(OAc)2-catalyzed dinitration reactions with Bi(NO3)3·5H2O in trifluoroethanol (TFE) and trifluoroacetic acid (TFA), we have developed an efficient and practical method for the synthesis of secondary dinitro-aromatic amines. The products could be applied to the preparation of 5-amine-N-methyl-benzimidazolone, the azo-dyes, economic advantages. The method has also been expanded to the dinitration reaction of
利用Pd(OAc)2与Bi(NO 3)3 ·5H 2 O在三氟乙醇(TFE)和三氟乙酸(TFA)中催化的硝化反应,我们开发了一种高效且实用的方法来合成仲二硝基-芳香胺。该产品可用于制备5-胺-N-甲基-苯并咪唑酮,具有偶氮染料的经济优势。该方法还扩展到某些叔芳族胺的硝化反应。
