Abstract

Ligand design has garnered significant attention in catalytic reaction development. This study reports the synthesis of novel polyazo ligands and their application in heterogeneous catalysis for the efficient and sustainable synthesis of diverse organic compounds. A novel pyrimidinyl pyrazole-based porous organic polymer was designed and synthesized. The resulting corresponding manganese composite PME@Mn was subsequently prepared and evaluated for its catalytic activity in the synthesis of quinazolinones and triazine derivatives through the acceptorless dehydrogenation coupling. It was disclosed that PME@Mn catalytic system exhibited quite broad substrate scope and high stability. In addition, this PME@Mn catalyst could be recycled and reused without a manifest loss of catalytic activity for at least five times and revealed potential application value.

PME@Mn作为无受体脱氢偶联合成喹唑啉酮和三嗪衍生物的有效催化剂
配体设计在催化反应发展中引起了极大的关注。本研究报道了新型多偶氮配体的合成及其在多相催化中的应用,以高效、可持续地合成多种有机化合物。设计并合成了一种新型的嘧啶基吡唑基多孔有机聚合物。随后制备了相应的锰复合材料PME@Mn,并通过无受体脱氢偶联对其在喹唑啉酮和三嗪衍生物合成中的催化活性进行了评价。结果表明,PME@Mn催化体系具有广泛的底物范围和较高的稳定性。此外,该PME@Mn催化剂可循环使用至少5次而不会出现明显的催化活性损失,具有潜在的应用价值。图形抽象

期刊介绍: Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
