Abstract

A visible-light-induced oxidation of alcohols generates alkoxyl radicals mediated by iodine(III) reagents under mild reaction conditions. The β-fragmentation of alkoxyl radicals enables selective C(sp3)-C(sp3) bond cleavage and alkynylation/alkenylation reactions with various strained cycloalkanols and linear alcohols.
