A novel and efficient method has been developed for the construction of an aromatic-phosphorus (Ar-P) bond under visible light irradiation using Cu2O/TiO2 nanoparticles as inexpensive and available photocatalysts. This protocol is a simple system without the use of any base, ligand, oxidant, or special conditions. This is the first report for the synthesis of arylphosphonates from arylhydrazines in visible light irradiation.

In this work, we developed a ligand- and base-free visible-light-mediated protocol for the photoredox syntheses of arylphosphonates and, for the first time, alkyl phosphonates. Zinc phthalocyanine-photocatalyzed Csp2-P and Csp3-P bond formations were efficiently achieved by reacting aryl/alkylhydrazines with trialkylphosphites in the presence of air serving as an abundant oxidant. The reaction conditions tolerated a wide variety of functional groups.

A novel CuO-catalyzed coupling reaction of arylhydrazines with trialkyl phosphites to afford arylphosphonates is described. The reaction proceeded at 80 C in air without external reductants, oxidants, and ligands.

Peracid oxidation of triester and related phosphorothionates and diester phosphorothioic acids with excess magnesium monoperoxyphthalate in water gives, among other products, dialkyl hydrogenphosphonates in yields of up to 70percent.Hydrogenphosphonate formation is facilitated by the presence of a good leaving group in the starting material.
