Hypervalent alkylsilicates represent new and readily accessible precursors for the generation of alkylradicalsunder photoredox conditions. Alkylradicals generated from such silicates serve as effective hydrogen atom abstractors from thiols, furnishing thiyl radicals. The reactive sulfur species generated in this manner can be funneled into a nickel-mediated cross-coupling cycle employing aromatic

A ligand‐free, CuI‐catalyzed protocol was developed for the one‐step preparation of Michael adducts of aromatic thiols in high yields by reacting a mixture of an arylhalide and an electron‐deficientalkene with sodiumiso‐propylxanthogenate.
