Front Cover: Visible-Light-Induced Desulfurative Coupling of Alkyl Benzothiazolyl Sulfides with Electron-Deficient Alkenes/Alkynes: Dual Role of Base-Activated Hantzsch Esters (ChemCatChem 3/2025)

Abstract

The Front Cover illustrates the generation of carbon radicals through the cleavage of carbon–sulfur bonds in alkyl benzothiazolyl sulfides by using Hantzsch ester. In their Research Article (DOI: 10.1002/cctc.202401427), T. Sengoku and co-workers report how they successfully achieved this radical generation under blue light by two methods: one employing caesium carbonate and the other combining 4DPAIPN with potassium carbonate. This approach provides a more direct synthetic route by avoiding the preparation of sulfone intermediates and demonstrates its utility in the synthesis of C-glycoside.
