Photocatalytic direct hydrogen atom transfer (d-HAT) is a synthetically important strategy to convert C–H bonds to useful C–X bonds. Herein we report the synthesis of an anthraquinone-based two-dimensional covalent organic framework, DAAQ-COF, as a recyclable d-HAT photocatalyst for

Anthraquinone was introduced into a metal−organic framework for the synergistic photoactivation of the C(sp3)−H bonds and molecular oxygen by integrating hydrogen atom transfer and energy transfer ...

Direct photocatalyzed hydrogen atom transfer (d-HAT) can be considered a method of choice for the elaboration of aliphatic C–H bonds. In this manifold, a photocatalyst (PCHAT) exploits the energy o...

Anthraquinone (AQ), an effective hydrogen atom transfer catalyst, is limited in photocatalytic applications due to its dimerization. In this study, a simple 3-(3-(dimethylamino) propyl)-1-ethylcarbodiimide hydrochloride/ N -hydroxysuccinimide (EDC/HNS) assisted linking strategy was developed to covalently graft AQ–COOH onto C 3 N 4 (CN).

The adoption of hydrogen atom transfer (HAT) in a photocatalytic approach, in which an excited catalyst is responsible for substrate activation, offers unique opportunities in organic synthesis, enabling the straightforward activation of R–H (R = C, Si, S) bonds in desired reagents.
