emphasizes Fe-promoted cross-electrophile allylation of tertiaryalkyl oxalates with allyl carbonates that generates all C(sp3)-quaternary centers. The reaction involves fragmentation of tertiaryalkyl oxalate C-O bonds to give tertiaryalkyl radical intermediates, addition of the radicals to less hindered alkene terminals, and subsequent cleavage of the allyl C-O bonds. Allylation with 2-aryl substituted
