General Overview on Recent Advance in Light-Induced Cu-I/II Photoredox Catalysis without Metal Co-Catalyst - Abstract
The synergistic fusion of photoredox catalysis and transition-metal catalysis denominated metallaphotoredox reaction. Over the past decades, the
merging of metal catalysis and photoredox catalysis has surfaced as a diverse and powerful technique in the production of challenging molecular synthesis.
The vast dominance of photoredox concepts exploits heavy, precious and expensive metals. Iridium or ruthenium-based complexes obey single-electron
reductants or oxidants in their photoexcited states. Thus, copper-based photocatalysts have rapidly sprung up in photochemistry due to their non-toxicity,
abundance, low price, and novel properties, including inner coordination sphere mechanisms. Nevertheless, they exhibit tunable redox characteristics in their
excited states, allowing stereoinduction accommodating flexible ligand architecture. Multiple accessible oxidation states are being accomplished for facile
reductive elimination, oxidative addition, rapid radical capture and C?C/ C?N/ C?O/ C?S/ C?X cross-coupling reactions. We notice that there are plenty
of research done on the concept of synergistic fusion of photo-redox and copper catalysis. Specifically, on this account we describe the latest advancements
in light-mediated merged copper-photoredox catalysis as initiation in organic transformations, focusing on substrate scope, limitations, mechanistic paradigms,
and various applications. This review covers the literature from 2018 to 2024.
