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 heterogeneous catalyst for the Hirao reaction of aryl halides and dialkyl phosphites or diphenylphosphine oxide with excellent recyclability, reusability, and retention of crystallinity.

An efficient protocol for the cross coupling of styrenyl/aryl halides and H-phosphinate has been developed using a unique Co/Cu catalytic system in the absence of any additional ligand for the first time. A library of diversely functionalised styrenyl/ary

A new method for copper-catalyzed P-C bond formation through reaction of phosphorus nucleophiles with diaryliodonium salts at room temperature is described. Most target products are obtained with this method in high yields within a short reaction time of 10 min. It can be easily adapted to large-scale preparations. When unsymmetrical iodonium salts are employed, nucleophilic substitution occurs preferentially on the sterically hindered aromatic ring or the more electron-deficient ring.

Potassium and sodium salts of diphenylphosphine add to nitroarenes in the position ortho and para to the nitro group. Subsequent oxidation of σH-adducts with potassium permanganate gave diphenyl(nitroaryl)phosphine oxides. Georg Thieme Verlag S
