PME@Mn as the Effective Catalyst for the Synthesis of Quinazolinones and Triazine Derivatives Through Acceptorless Dehydrogenation Coupling
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.
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.
