ConspectusClassical education in organic chemistry and catalysis, not the least my own, has centered on two-electron transformations, from nucleophilic attack to oxidative addition. The focus is well-founded, as this brand of enabled incredible feats synthesis, development life-saving pharmaceuticals production ubiquitous commodity chemicals. With that said, approach many ways complementary nature, where enzymes frequently make use single-electron "radical" steps achieve challenging reactions with exceptional selectivity, including light detection C-H hydroxylation. While power radical elementary undeniable, fundamental understanding of─and ability apply─these catalysis remains underdeveloped, constraining palette which chemists can new reactions.Motivation remedy traditional underemphasis been intensified by runaway success outer-sphere photoredox only confirming versatility radicals anthropogenic but also teaching value robust well-understood catalytic cycles for reaction design. Indeed, I would argue fueled strong its underlying steps, consideration transfer (SET) energetics allowing be designed

Quinuclidine‐Catalyzed Electrochemical Minisci Acylation of N‐Heteroarenes with Acylhydrazines

ChemCatChem, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 3, 2024

Abstract The quinuclidine (Qu)‐catalyzed activation of acylhydrazines to afford the corresponding acyl radicals remains an unmet challenge. To address this challenge, we report a synergistic strategy by combining electro‐oxidation with Qu‐based HAT catalysis. Enabled strategy, electrochemical Minisci acylation N ‐heterocycles was realized for first time.
