Electrophotocatalysis Versus Indirect Electrolysis: Electrochemical Selenocyclization of 3‐Aza‐1,5‐dienes Facilitated by Energy Transfer, Direct Photolysis or N‐Hydroxyphthalimide

Chemistry - A European Journal, Journal Year: 2024, Volume and Issue: 30(36)

Published: April 23, 2024

Three hybrid electrochemical protocols, which involve the energy transfer, direct photolysis and N-hydroxyphthalimide catalyst, respectively, are presented for selenylation/cyclization of fragile substrates 3-aza-1,5-dienes with diorganyl diselenides to afford 3-selenomethyl-4-pyrrolin-2-ones. The two electrophotocatalytic reactions indirect electrolysis one both regioselective external-oxidant- transition-metal-free, associated a broad substrate scope high Se-economy, all three methods amenable gram-scale syntheses, late-stage functionalizations, sunlight-induced experiments all-solar-driven syntheses.

Photoelectrochemical Cerium Catalysis via Ligand-to-Metal Charge Transfer: A Rising Frontier in Sustainable Organic Synthesis

Synthesis, Journal Year: 2023, Volume and Issue: 55(18), P. 2860 - 2872

Published: Feb. 28, 2023

Abstract Photoelectrochemical cerium catalysis is an emerging and rapidly developing strategy in organic synthetic. A sustainable platform being constructed by combining the concerted energy transfer from light electricity to with ligand-to-metal charge of excited state CeIV species. With this powerful strategy, hard oxidized substrates can be activated under mild conditions, contributing broad functional group compatibility. Such as, carboxylic acids, alcohols, Cl anion deliver corresponding radicals via formal single electron (SET) a low oxidation potential. Further cooperation other synthetic strategies, including alkoxy radical promoted hydrogen atom (HAT) β-scission, leads functionalization inert C(sp 3)–H, Si–H, C–C bonds pathway. In review, recent advances photoelectrochemical are described. More importantly, as field features some unique advantages, but rarely explored, we hope chemists will pay more attention catalytic system. 1 Introduction 2 Activation Carboxylic Acids 3 Alcohols 3.1 Alkoxy Radical Involved Hydrogen Atom Transfer 3.2 Promoted β-Scission 4 Formal Single-Electron Oxidation Anion 5 Conclusions Outlook
