The development of heteroaromatic conjugated porous polymers (H-CPPs) have received enormous research interests, because the important functional roles heteroatoms in photocatalysis and proton conduction. However, due to synthetic challenges deriving from stable structures, structural diversity methods them are still limited. Herein, a new type H-CPPs, covalent pyrimidine frameworks (CPFs), via an efficient tandem polycondensation reaction between aldehyde, acetyl, amidine monomers is reported. resulting CPFs bridged by units, rich nitrogen atoms can be structurally regulated on demand. shown active photocatalysts for hydrogen evolution methanol photo-thermo-catalysis process, achieving excellent rate 5282.8 µmol h-1 g-1 . further processed into mixed matrix membrane, displaying conductivity 1.30 × 10-2 S cm-1 at 413 K under anhydrous condition.

Abstract Multicomponent reactions (MCRs) have emerged as powerful tools in synthetic chemistry for the efficient synthesis of diverse molecular scaffolds, particularly nitrogen‐containing heterocycles. Despite their numerous advantages, use transition metal catalysts or additives MCRs can present limitations due to cost, toxicity, and environmental concerns. In recent years, there has been a growing interest metal‐free N ‐heterocyclic compounds. This review provides comprehensive concise overview advancements valuable ‐heterocycles over past five years. The is systematically organized, categorizing discussed based on size heterocyclic ring number nitrogen atoms. Only that result formation rings containing at least one atom are included, while derivatization using falls outside scope this review. By highlighting developments field, aims showcase potential significance sustainable strategies accessing elimination metals not only simplifies reaction conditions but also contributes greener more environmentally friendly approaches. serves resource researchers interested design application

An efficient, facile, and eco-friendly synthesis of pyrimidine derivatives has been developed. It involves a [3 + 2 1] three-component annulation amidines, ketones, one carbon source. N,N-Dimethylaminoethanol is oxidized through C(sp3)-H activation to provide the donor. One C-C two C-N bonds are formed during oxidative process. The reaction shows good tolerance many important functional groups in air, making this methodology highly versatile alternative, significant improvement existing methods for structuring framework, especially 4-aliphatic pyrimidines.
