cleavage and radical alkynylation of α‐phosphorus alcohols to construct phosphonoalkynes is reported. The phosphorus radical is generated upon P−C bond cleavage reaction via the alkoxyl radical through photoredox catalysis with cyclic iodine(III) reagents. Various arylphosphinoyl‐, alkylphosphinoyl‐, phosphonate‐, and phosphonic amide alcohols serve as radical phosphorus precursors to construct phosphonoalkynes
