摘要:由于扩散受阻,多孔催化材料的应用仅限于相对简单的具有小基材的有机转化.在此,我们报告了一种降维策略,以构建二维金属有机骨架 (Mof) Zr 6 Otf-Btb,其具有 96% 可接近的路易斯酸性位点,如通过庞大的路易斯碱新戊腈探测.近无基材无障碍,锆6光学传递函数-Btb优于类似路易斯酸性的两个三维mof同行(锆6光学传递函数-Bpdc和zr 6为四氢喹啉的结构催化位阻多组分反应(mcrs)光学传递函数-Btc)和具有高周转数 (Ton) 的氮丙啶羧酸衍生物.锆6Otf-Btb 也优于均质基准 Sc(Otf) 3,其 Ton 高近 14 倍,催化剂寿命长 9 倍.此外,这些基于 Zr 的路易斯酸性 Mof 中的拓扑-活性关系通过比较它们的路易斯酸度,路易斯酸性位点的数量和空间可及的路易斯酸性位点来合理化.zr 6 Otf-Btb 成功地用于通过 Mcr 构建多种生物活性分子,并具有出色的

标题 :Synthesis of a triangulene ring system and derivatives thereof

摘要:A three step synthesis of the 8,12-dihydro-4H-dibenzo[cd,mn]pyren-3a 2 -ylium cation (triangulenium cation) is effected by cascade cyclization of a tetra-benzyl alcohol precursor in triflic acid solution. This cation is easily observed by NMR and optical spectroscopy. Quenching of the cation into basic solutions or by hydride transfer from triethylsilane provides access to stable dihydro and tetrahydro[3]triangulenes. This route makes several [3]triangulene precursors more readily available for development of new applications in the field of molecular electronics.
