摘要:已经通过钯催化使碘代芳基苯甲酰胺直接均相偶联,以高收率合成了一系列对称的二酰胺基联芳基.在相似条件下,没有从两种不同的碘代芳基苯甲酰胺的反应混合物中分离出交叉产物.但是,仅在2-碘-N的情况下-苯基苯甲酰胺,分子内偶联产物菲啶酮已作为次要产物与主要的分子间偶联产物一起被分离出来.通过这种偶联方法已经合成了联苯手性二酰胺.该偶联反应还与官能化杂环化合物的还原二聚作用一起很好地起作用.因此,已经有效地合成了6,6'-二戊酰氨基-3,3'-联吡啶和6,6'-二甲基-2,2'-联吡啶.在两种情况下,已经解决了x射线晶体结构,以建立对称和手性的二氨基联芳基及其超分子网络的结构.

摘要:Methods and compositions related to the synthesis of photosensitizers of titanium dioxide performed in situ, stepwise, in the solid state, and directly on the surface of the titanium dioxide semiconductor material. The method is generally accomplished by first absorbing an anchor ligand onto the titanium dioxide semiconductor material, then adding an appropriate transition metal, and finally adding one or more secondary ligands to complete the synthesis of the transition metal complex or sensitizer.
