Synthetic Utility of Alkyl tert-Butyl Peroxides in a Copper-Catalyzed Radical Functionalization

Alkyl tert-butyl peroxides are prepared from the corresponding tert-alkyl precursors and tert-butyl hydroperoxide in the presence of a promoter. These substrates can be utilized in a mild copper-catalyzed radical functionalization that utilizes several coupling partners and has a broad substrate scope. A mechanistic study suggests that alkyl radical species participate in the coupling reactions.
