摘要:
以4-三氟甲基苯甲醛、4'-硝基苯乙酮和醋酸铵为原料,在冰醋酸介质中,通过改进的Chichibabin反应得到了二硝基化合物4-(4-三氟甲基苯基)-2,6-二(4-胺基苯基)吡啶(TMPBNPP),继而用Pd/C和水合肼将TMPBNPP进行还原,成功合成了一种新型含吡啶环和三氟甲基侧基的芳香二胺4-(4-三氟甲基苯基)-2,6-二(4-胺基苯基)吡啶(TMPBAPP),2步反应总收率为48;,并用核磁共振谱、红外光谱和X-射线衍射等手段对其结构进行了分析表征.
Abstract:
A novel aromatic diamine containing a pyridine heterocyclic ring and a trifluoromethyl substituent,4-(4-trifluoromethylphenyl)-2,6-bis(4-aminophenyl)pyridine(2)was successfully synthesized in by a modified Chichibabin reaction of 4-trifluoromethylbenzaldehyde,4'-nitroacetophenone and ammonium acetate in glacial acetic acid,followed by a reduction of the resulting dinitro compound,4-(4-trifluoromethylphenyl)-2,6-bis(4-aminophenyl)pyridine(1)with Pd/C and hydrazine monohydrate.The new diamine 2 was obtained in overall yield of about 48%(based on compound 4-trifluoromethylbenzaldehyde).The structure of the target compound was characterized by H NMR,IR,elemental analysis and X-ray diffraction measurements.
