Triazine Frameworks for the Photocatalytic Selective Oxidation of Toluene.
Angew. Chem. Int. Ed. 2024;

Key words
triazines - COF - thiophenes - photocatalysis - oxidation - toluene
Significance
A triazine-based covalent organic framework bearing thiophene units CTF-Th-0 was found
to promote the photocatalytic oxidation of toluenes with molecular oxygen under blue
LED irradiation to give the corresponding benzaldehydes. Alkylbenzenes gave acetophenones
under similar conditions.
Comment
A series of CTF-Th-X was prepared through the super acid-catalyzed polymerization
of dicyanothiophenes Th-0, -1, -2, respectively, with a silica template. In the photooxidation
of toluene, used CTF-Th-0 was recovered by centrifugation and reused four times without
a significant loss of its catalytic performance.
