A novel and convenient palladium‐catalyzed cross‐coupling reaction of H‐phosphonate diesters with sodiumarylsulfinates was developed via desulfitation in the presence of silver carbonate and tetra‐butylammonium chloride. This method is highly efficient and provides a rapid access to a broad spectrum of arylphosphonate diesters in good to excellent yields.
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 PdII. The obtained Pd-supported COF nanoparticles catalyst (defined as Pd/TFPT-Azine-COF) was found to be an efficient heterogeneouscatalyst for the
