Selective P?C(sp3) Bond Cleavage and Radical Alkynylation of α-Phosphorus Alcohols by Photoredox Catalysis

Herein the first P?C(sp3) bond 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 for the first time.

PHOTOLYSIS OF DIPHOSPHONATE DERIVATIVES HAVING AROMATIC RING ASSEMBLIES

Upon UV-irradiation in methanol the diphosphonates fully substituted with aromatic rings give biaryls and aryl(dimethoxy)carbene derivatives in quantum yield of 0.01-0.03.The mechanism of the selective α,α-elimination of aryl groups was discussed.
