cleavage/alkynylation of cycloalkylamides for the aminoalkyne synthesis undermildphotoredoxcatalysisconditions. γ- and δ-Aminoalkynes with versatile alkyne and amine substituents are efficiently constructed from cyclopropylamides and cyclobutylamides via amidyl radicals enabled by hypervalentiodine(III) reagents. The catalytic amount of cyclic iodine(III) BI’-OAc facilitated the single-electron oxidation and ring-opening
