摘要
Three zincand cobaltcoordination polymers,namely{[Zn_(2)(μ_(6)-adip)(phen)_(2)]·4H_(2)O}_(n)(1),{[Co_(2)(μ_(6)-adip)(bipy)_(2)]·4H_(2)O}_(n)(2),and[Co_(2)(μ4-adip)(μ-bpa)_(2)]_(n)(3)have been constructed hydrothermally using H4adip(H4adip=5,5′-azanediyldiisophthalic acid),phen(phen=1,10-phenanthroline),bipy(bipy=2,2′-bipyridine),bpa(bpa=bis(4-pyridyl)amine),and zinc and cobalt chlorides at 160℃.The products were isolated as stable crystalline solids and were characterized by IR spectra,elemental analyses,thermogravimetric analyses,and single-crystal X-ray diffrac-tion analyses.Single-crystal X-ray diffraction analyses revealed that three compounds crystallize in the orthorhom-bic system Pnna(1 and 2)or P21212(3)space groups.All compounds exhibit 3D frameworks.The catalytic perfor-mances in the Henry reaction of these compounds were investigated.Compound 3 exhibited an effective catalytic activity in the Henry reaction at 70℃.CCDC:2339391,1;2339392,2;2339393,3.
利用水热合成方法,选用5-((3,5-二羧基苯基)氨基)苯-1,3-二甲酸配体(H4adip)与菲咯啉(phen)、2,2′-联吡啶(bipy)或双(4-吡啶)胺(bpa),分别与ZnCl_(2)和CoCl_(2)·6H_(2)O在160℃温度下反应,合成了3个三维配位聚合物{[Zn_(2)(μ_(6)-adip)(phen)_(2)]·4H_(2)O}_(n)(1)、{[Co_(2)(μ_(6)-adip)(bipy)_(2)]·4H_(2)O}_(n)(2)和[Co_(2)(μ4-adip)(μ-bpa)_(2)]_(n)(3)。这些配合物为稳定的晶体。通过红外光谱、元素分析、热重分析和单晶X射线衍射分析对其进行了表征。单晶X射线衍射分析表明,3个配合物的晶体属于正交晶系Pnna(1和2)和P21212(3)空间群。配合物1^(3)都呈三维结构。考察了这些配合物在Henry反应中的催化活性。研究表明,配合物3在70℃下对Henry反应表现出有效的催化活性。同时对反应参数进行了优化,对底物范围也进行了研究。
