Alkyl radicals generated from hypervalent alkylsilicates serve as effective hydrogen atom abstractors from thiols, furnishing thiyl radicals. A subsequent nickel-mediated cross-coupling with aromatic bromides provides thioethers. This thioetherification of various aryl and heteroaryl bromides with a diverse array of thiols tolerates a wide range of functional groups due to the S-H selective H atom abstraction event.
