Heterogeneous photocatalysis has emerged as a green and sustainable technique in organic synthesis. Developing highly effective heterogeneous photocatalysts that outperformed classical ruthenium-/iridium-based homogeneous ones for the visible-light mediated organic transformations is actively pursued by chemists but remains challenging. Herein, a modified carbon nitride-based heterogeneous photocatalytic system for both decarboxylative addition and reductive dimerization of para-quinone methides has been developed. The potassium-intercalated carbon nitride (CN-K) facile prepared by the direct KCl-induced structure remodeling of bulk g-C3N4 exhibited remarkable catalytic activity. The catalyst loading can be decreased to 0.025-0.25 mg/mL, which is significantly lower than that in homogeneous photocatalysis. Studies on the structure characterizations and photoelec. properties of CN-K and g-C3N4 imply that the enhanced activity of CN-K was attributed to its K-intercalated poly(heptazine)-based structure and existed as small lamellar nanocrystallites, thus leading to enhanced optical absorption, improved electron-hole separation, and easy dispersion in polar solvents. The heterogeneous nature and mild reaction conditions of this protocol allow for good catalyst recyclability, broad substrate scope, scale-up in a continuous flow, and applications to the valued target synthesis.
ACS Sustainable Chemistry & Engineering published new progress about Agglomerates (clustered mass) (agglomerates of g-C3N4 vs. nanosheets of CN-K). 104-01-8 belongs to class isoquinoline, name is 4-Methoxyphenylacetic acid, and the molecular formula is C9H10O3, SDS of cas: 104-01-8.
