1,4-二甲基-2,5-二-1H-1,2,4-双三唑三维锌配合物单晶与应用
Abstract:
本发明公开了1,4?二甲基?2,5?二?1H?1,2,4?双三唑三维锌配合物单晶及其制备方法与应用，其结构：[Zn(L)(tpa)]·1.5DEAC，其中，L=1?(2,5?二甲基?4?(1H?1,2,4?三唑?1?基)苯基)?1H?1,2,4?三唑；tpa=对苯二甲酸；DEAC=N,N'?二乙基乙酰胺。同时还公开了单晶的制备方法。它是采用常温挥发法，即L、tpa和Zn(NO3)2·6H2O在水和DEAC的混合溶剂中搅拌半小时后过滤，滤液常温挥发两周后得到适合X?射线单晶衍射的无色块状晶体。其中L:tpa:Zn(NO3)2·6H2O的摩尔比为1:1:1。本发明进一步公开了1,4?二甲基?2,5?二?1H?1,2,4?双三唑三维锌配合物单晶专属性用于对氟苯硼酸生成4,4'?二氟联苯的催化剂方面的应用。
Abstract(English):

The invention discloses a 1,4-dimethyl-2,5-di-1H-1,2,4-bis (triazol 1 yl) three-dimensional zinc complex single crystal and a preparation method and an application thereof. A structure is [Zn(L)(tpa)] 1.5DEAC, wherein L=1-(2,5-dimethyl-4-(1H-1,2,4-triazole-1-yl)phenyl)-1H-1,2,4-triazole; tpa=terephthalic acid; DEAC=N,N'-dimethylacetamide. The invention also discloses the preparation method of the single crystal. The preparation method is a normal-temperature volatilizing method, comprising the following steps of stirring L, tpa and Zn(NO3)2 6H2O in a mixed solvent of water and DEAC for 0.5h, filtering, and volatilizing a filtrate for two weeks at the normal temperature, so as to obtain the colorless blocky crystal which is suitable for X-ray single crystal diffraction, wherein the molar ratio of L:tpa:Zn(NO3)2 6H2O is 1:1:1. The invention further discloses the application of the 1,4-dimethyl-2,5-di-1H-1,2,4-bis (triazol 1 yl) three-dimensional zinc complex single crystal special for fluorophenylboronic acid to generate a 4,4'-difluorobiphenyl catalyst.
