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.

On/Off O2 Switchable Photocatalytic Oxidative and Protodecarboxylation of Carboxylic Acids

“…Recently, our laboratory started to design and synthesize a new set of semiconductor photocatalysts for specific transformations. − The synthesis of two different sets of organic compounds (alkanes and aldehydes/ketones) is very important, and using previously reported methods for decarboxylation of carboxylic acids to generate open-shell radicals with various photoredox catalysts, the idea to design a switchable photocatalyst came to our mind.…”

New Approaches toward Building Csp−P bond: A Two‐Decade Overview

“…Similarly, TiO 2 /Cu 2 O nanoparticles were easily prepared under solvothermal conditions from a mixture of copper(II) acetate monohydrate, water and PEG-300 followed by subse-quent addition of tetrabutyl titanate. [82] Due to its narrow band gap, Cu 2 O is able to absorb visible light, forming electron/hole (e À /h + ) pairs. Reaction of electron-rich PÀ H derivatives with holes (h + ) generated phosphorus-centered radicals by single electron transfer.…”

Visible‐Light‐Induced C‐P‐Bond Formation Using Reduced Graphene Oxide Decorated with Copper Oxide/Zinc Oxide (rGO/CuO/ZnO) as Ternary Recyclable Nanophotocatalyst

“…So, the need to introduce new synthetic strategies for the synthesis of titled compounds under more benign conditions is still felt. Recently, our research group reported the use of aryl hydrazines for the synthesis of aryl phosphonates in the presence of Cu 2 O/TiO 2 NPs as photocatalyst for the first time [24] . Given that the weight percent of Cu is about 5 times Ti and the oxidation of Cu +1 to Cu +2 makes the photocatalyst ineffective (after a while) (Scheme 1, A).…”
