以水为介质,氯化三乙基苄基铵(TEBAC)为相转移催化剂,在回流条件下,N-(4-溴苯亚甲基)-2-萘胺与4-羟基香豆素反应,合成了标题化合物C26H16BrNO2,其结构通过IR,1HNMR,元素分析及单晶X射线衍射分析确定.结果表明:晶体属于单斜晶系,空间群P21/c,a=0.73681(8)nm,b=1.35483(14)nm,c=1.9662(3)nm,β=100.372(4)°,Mr=454.31,V=1.9307(4)nm3,Dc=1.563g/cm3,Z=4,μ(MoKα)=0.2153cm-1,F(000)=920.晶体结构用直接法解出,使用全矩阵最小二乘法对原子参数进行修正,最终的偏离因子R1=0.0446,Rw=0.0968.
The title compound C26H16BrNO2 has been synthesized by the reaction of N-（4-bromophenylidene）naphthalen-2-amine（1） with 4-hydroxycoumarin in water at reflux, using triethylbenzylammonium chloride（TEBAC） as phase transfer catalyst. Its structure was characterized by IR,^1HNMR and elemental analysis, and further confirmed by single crystal X-ray diffraction. The crystal is monoclinJc, space group P21/c with a=0.73681（8）nm,b=1.35483（14）nm,c=1.9662（3）nm,β=100.372（4）°,Mr=454.31,V=1.9307（4）nm^3,Dc=1.563g/cm^3,Z=4,μ（Mo Ks）=0.2153 cm^-1,F（000）=920. The structure was solved by direct methods and refined by full-matrix least squares method to the final R1 =0. 044 6, Rw =0. 096 8.
