Photoactivated Pyridine Directed Fluorination through Hydrogen Atom Transfer

Site-selective benzylic C–H hydroxylation in electron-deficient azaheterocycles

“…2c). 61–64 Such pre-coordination of a strong oxidant to the heterocycle allows for C–H activation by proton-coupled electron transfer (PCET). We wondered whether coordination complexes analogous to 15 might also allow for site-selective C–H activation by proton-coupled electron transfer in contexts beyond fluorination.…”
