Cu2O/TiO2 nanoparticles as visible light photocatalysts concerning C(sp2)–P bond formation

Abstract

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.
