Starting from mononitrotetrakis(iodophenyl)methane as monomer, we report the preparation of the first pre‐functionalised porous aromatic frameworks (PAFs) and their application as supports for organometallic catalysts. Neutral coordinate imino‐pyridine Schiff base (PAF‐NPy) or chiral bis‐amino (PAF‐NPro) ligands were obtained by post‐synthetic treatment of PAF‐NH2 and treated with copper(I) or rhodium(I)
从单硝基四(碘代苯基)甲烷作为单体开始,我们报道了第一个预功能化的多孔芳族骨架(PAF)的制备及其在有机金属催化剂载体中的应用。通过PAF-NH 2的后合成处理并用铜(I)或铑(I)处理得到中性配位的亚氨基吡啶席夫碱(PAF-NPy)或手性双氨基(PAF-NPro)配体。相应的负载型过渡金属催化剂。所制备的PAF-NN-M催化剂显示出与相应的均相催化剂相似的活性和选择性,并且很容易从反应介质中除去并循环使用,而不会损失活性或选择性。
