摘要
以三苯胺为原料,通过改进的乌尔曼反应高效地合成了三-(4-吡唑基)苯基胺(1),其结构经X-射线单晶衍射仪,1H NMR,IR,MS和元素分析表征。1属于正交晶系,Pccn空间群,晶胞参数:a=23.394(7),b=34.021(9),c=11.719(3)。分子间通过氢键和弱的π┈π作用相互连接。
Tris-(4-pyrazolyl)phenylamine (1) was efficiently synthesized from trisphenylamine by improved Ullmann reaction. The structure was characterized by single crystal X-ray diffraction, ^1H NMR, IR, MS and elemental analysis. 1 belongs to orthorhombie system with space group Pccn, a = 23. 394 (7) A, b = 34. 021 (9)A, c = 11.719 (3)A. There are weak hydrogen bonds and π - π interactions between molecules in the crystal.
