Abstract
A simple azine‐linked covalent organic framework (COF) with high thermal and chemical stabilities has been prepared by using deep eutectic solvent (DES) as green media. The as‐synthesized COF was employed as heterogeneous ligand for immobilization of Pd II . The obtained Pd‐supported COF nanoparticles catalyst (defined as Pd/TFPT‐Azine‐COF) was found to be an efficient heterogeneous catalyst for the Hirao reaction of aryl halides and dialkyl phosphites or diphenylphosphine oxide with excellent recyclability, reusability, and retention of crystallinity.
