A palladium-catalyzed intermolecular polarity-mismatched addition of unactivated alkyl radicals to unactivated alkenes was developed for the first time. In the two-component dicarbofunctionalization, a variety of primary, secondary, and tertiary unactivated alkyl halides regioselectively reacted with various unactivated olefins. A series of structurally complex heteropolycycles decorated with a quaternary
