Photoelectrocatalytic organic synthesis: a versatile method for the green production of building-block chemicals

Abstract

The rising energy crisis and environmental problems are urging the development of more sustainable organic synthetic methods. Photoelectrocatalytic organic synthesis (PECOS) is emerging as an attractive strategy because it utilizes...

Photoelectrochemical Ni-Catalyzed Cross-Coupling of Aryl Bromides with Amine at Ultra-Low Potential

“…Even for bulky substituent such as tert-butyl or carbazole, the reaction takes place with moderate yields (22,23). Similar tolerance is observed for the meta-and multi-substituted substrates (24)(25)(26)(27)(28)(29)(30)(31). Bromobenzene, bromonaphthalene and some more complicated bromated (hetero) aromatic compounds were further tested and fair to good yields were observed (32)(33)(34)(35)(36)(37)(38).…”

Tandem Photooxidation/Acetalization of Alcohols to Acetals/Ketals with Sulfur‐doped Carbon Nitride

“…achieved chemoselective acetalization with Ni (II) complexes under neutral conditions. There is an increasing realization to utilize renewable energy sources (sunlight) to drive targeted chemical reactions while avoiding waste generation and the need for extensive workup [28,29] …”

“…There is an increasing realization to utilize renewable energy sources (sunlight) to drive targeted chemical reactions while avoiding waste generation and the need for extensive workup. [28,29] Recently carbon nitride, the π-conjugated layered framework material comprising earth-abundant elements carbon and nitrogen, has stirred interest owing to its ability to harvest visible light energy for chemical synthesis. [5,[30][31][32] According to the literature, reductive activation of oxygen from the air for photo oxidation of alcohols and photo-synthesis of other fine chemicals over carbon nitride has been shown.…”

WO3‐based Materials for Photocatalytic and Photoelectrocatalytic Selective Oxidation Reactions

“…Recently, the photoelectrocatalytic (PEC) process, which combines PC and anodic oxidation, has been recognized as an efficient method for selective oxidation reactions and promotes the separation of photogenerated electron-hole pairs by applying a bias potential. [13] WO 3 is a typical semiconductor constructing photoanodes for PEC oxidation reactions such as water oxidation, pollution degradation, and selective oxidation. PEC selective oxidation of organic compounds reduces reaction overpotential and produces value-added products.…”
