Abstract

A direct dehydroxylative radical alkylation reaction of tertiary alcohols with activated alkenes enables a facile and precise construction of all-carbon quaternary centers. The reaction tolerates a wide range of electrophilic coupling partners, including allylic carboxylates, aryl and vinyl electrophiles, and primary alkyl chlorides/bromides and leaves secondary/primary alcohols and phenols intact.
