摘要
用N-氨乙基哌嗪与醋酸锌反应合成了一种新颖的一维锌配位聚合物,采用红外光谱、元素分析、热重分析和X射线单晶衍射对其结构进行了表征和分析。该配位聚合物属于三斜晶系,空间群为Pī,晶体学参数为a=0.69461(13)nm,b=1.00951(19)nm,c=1.0751(2)nm,α=117.576(3)°,β=93.506(3)°,γ=94.231(3)°,V=0.6625(2)nm3,Z=2。在等量三乙胺存在下,该配位聚合物具有良好的催化性能。研究结果表明:当催化剂用量为5mol%时,在甲醇中催化对硝基苯甲醛与硝基甲烷反应可以得到94%产率的1-对硝基苯基-2-硝基乙醇产物。
A novel 1D zinc coordination polymer was synthesized by the reaction of zinc acetate to Naminoethylpiperazine. The structure of the polymer was characterized and analyzed by infrared spectroscopy,elemental analysis,TGA and X-ray single crystal diffraction. The polymer crystallized in the triclinic system with space group Pī,the crystallographic parameters: a = 0. 69461(13) nm,b = 1.00951(19) nm,c = 1. 0751(2) nm,α = 117. 576(3) °,β = 93. 506(3) °,γ = 94. 231(3) °,V = 0.6625(2) nm3,Z =2. The polymer exhibited excellent catalytic activity in the presence of equimolar triethylamine. The results showed that 1-p-nitrophenyl-2-nitroethanol product could be obtained in 94%yield when the polymer with 5mol% catalyst loading was used to catalyze the reaction of pnitrobenzaldehyde to nitromethane in methanol.
