Construction of covalent organic frameworks via the Mannich reaction at room temperature for light-driven oxidative hydroxylation of arylboronic acids

An increasing variety of organic reactions have been developed for the synthesis of more structurally stable and multifunctional COFs. Here, we report a class of β-ketamine linked covalent organic frameworks that were constructed through the CeCl₃-catalyzed multi-component Mannich reaction at room temperature. And the TAD-COF obtained based on this method could significantly promote the light-driven oxidative hydroxylation of arylboronic acids.
