Radical Stabilization-Driven Reactivity in Paracyclophane Ketoesters: Site-Selective Hydrogen Atom Transfer over Norrish Fragmentation
We report a radical-stabilization-driven photoreactivity of [2,2]paracyclophane (PCP) ketoesters that enables site-selective hydrogen atom transfer (HAT) under visible-light irradiation. The PCP ketoester enables free-radical photopolymerization under air, deep curing, and low toxicity. In combination with an iodoniu...
