Key Points

This study aims to investigate the reaction of dearomatized heterocycles with sulfur hexafluoride under specific lighting conditions.
Utilized Hantzsch ester and other dearomatized heterocycles as substrates.
Irradiated the reaction mixture with 390 nm LEDs.
Monitored the reaction for aromatization and fluoride ion release.
Dearomatized heterocycles successfully undergo aromatization when exposed to SF6 under LED light.
Reduction of SF6 occurs, resulting in the release of fluoride ions.

Implication

Mechanistic Analysis Reveals Aromatization of Dearomatized Heterocycles with Sulfur Hexafluoride, Suggesting New Pathways for Synthetic Chemistry.

Abstract

A Hantzsch ester, and other dearomatized heterocycles undergo aromatization in the presence of sulfur hexafluoride (SF6) upon irradiation with 390 nm LEDs, reducing SF6 and releasing fluoride ion. Two aryl...
