| 摘 要： | 以取代苯甲醛分别与丙二酸及丙二腈反应制备了两种3-羧酸香豆素及两种3-氰基香豆素,用IR、1HNMR、质谱、元素分析对产物进行了结构表征。3-羧基香豆素最优环合反应时间是72 h。经解析发现,3-羧基-6-氟-7-羟基香豆素(Ⅱa1)的晶体结构属三斜晶系,P-1空间群,晶胞参数:a=0.686 9(3)nm,b=0.699 6(3)nm,c=1.431 5(6)nm,Z=2,F(000)=310。最终偏离因子R=0.111 4,wR=0.309 0。晶体结构中存在π-π堆积作用。

| Abstract: | 3-Carboxy and 3-cyano coumarin were synthesized from substituted benzaldehyde and malonic acid or malononitrile.The structures were confirmed by IR,1HNMR,MS and element analysis.The optimal reaction time for preparing 3-carboxy coumarin is 72 h.The crystal of 3-carboxy-6-fluoro-7-hydroxy coumarin belongs to the triclinic system,space group P-1 with a=0.686 9(3) nm,b=0.699 6(3) nm,c=1.431 5(6) nm,Z=2,F(000)=310.The final R=0.111 4,wR=0.309 0.It shows that the crystal structure is connected by π-π stacking interactions. |
