Thioetherification via Photoredox/Nickel Dual Catalysis [PDF]
Organic Letters, 2016 Hypervalent alkylsilicates represent new and readily accessible precursors for the generation of alkyl radicals under photoredox conditions. Alkyl radicals generated from such silicates serve as effective hydrogen atom abstractors from thiols, furnishing thiyl radicals.
