Visible Light‐Induced Synthesis of Isoquino[2,1‐ a ]pyrimidine Derivatives Catalyzed by Covalent Triazine Frameworks

ABSTRACT A heterogeneous photocatalytic dehydrogenative system was developed based on covalent triazine frameworks (CTFs) for the visible light‐driven synthesis of isoquino[2,1‐ a ]pyrimidine derivatives under metal‐free, room temperature conditions, with H 2 as the sole byproduct. The CTF catalyst features excellent recyclability with negligible activity loss after four filtration‐recovery cycles.
