Palladium anchored on a covalent organic framework as a heterogeneous catalyst for phosphorylation of aryl bromides

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.

Non-metallic compd. Bisphosphonic acid crosslinked layered manufacturing method

PROBLEM TO BE SOLVED: To provide a novel noncrosslinking type layered phosphonic acid metal compound which has high crystallinity and a uniformly introduced multicomponent phosphonic acid and is free of a fluorine atom, and to provide a method for the production of the same.SOLUTION: The method for the production of the noncrosslinking type layered phosphonic acid metal compound includes a reaction step of reacting two or more monophosphonic acids or derivatives thereof having predetermined conditions with a metal source that can generate a hexacoordinated metal atom ion to be a central atom (M) of a metal oxide octahedron upon reaction in the presence of a sulfuric acid catalyst. The noncrosslinking type layered phosphonic acid metal compound obtained by the production method is also provided.

New type of metalloproteinase inhibitor: Design and synthesis of new phosphonamide-based hydroxamic acids

A series of phosphonamide-based hydroxamate derivatives were synthesized, and the inhibitory activities were evaluated against various metalloproteinases in order to clarify its selectivity profile. Among the four diastereomeric isomers resulting from the

SYNTHESIS OF PHOSPHONIC DICHLORIDES AND CORRELATION OF THEIR P-31 CHEMICAL SHIFTS

Various mono-substituted diethyl arylphosphonates were prepared in good yield by treatment of aryl bromides or iodides with triethyl phosphite in the presence of NiCl2 or alternatively, addition of the aryl grignard reagent to diethyl phosphorochloridate.
