Copper-Catalyzed Cross-Coupling of Alkyl and Phosphorus Radicals for C(sp3)–P Bond Formation

A CuI-catalyzed cross-coupling of alkyl- and phosphorus-centered radicals for C(sp3)-P bond formation is introduced. Diacyl peroxides, generated in situ from aliphatic acids and H2O2, serve as a source for alkyl radicals and also an initiator for the generation of phosphorus radicals from H-P(O) compounds.
