Novel p-iodobenzoate-based labelling reagents are shown to be effective photocaged
precursors for synthesizing biomolecular radicals site-selectively in the gaseous and
condensed phases. In vacuo, a single pulse of UV photons (266 nm) is sufficient to
quantitatively photolyse the C–I bond. In aqueous solutions, the photolysis half-life is
estimated to be 2.5 minutes when irradiating with a 15 W compact fluorescent lamp (254
nm).
