Title: Generation of radical-cations from naphthalene and some derivatives, both by photoionization and reaction with SO<sub>4</sub><sup>–</sup>˙: formation and reactions studied by laser flash photolysis
Abstract:Radical-cations from naphthalene and some derivatives have been generated in aqueous acetonitrile both by direct photolysis (with λ 248 nm light via biphotonic ionization) and via reaction with SO4–˙....Radical-cations from naphthalene and some derivatives have been generated in aqueous acetonitrile both by direct photolysis (with λ 248 nm light via biphotonic ionization) and via reaction with SO4–˙. The radical-cation reacts rapidly with the parent substrate (k ca. 108 dm3 mol–1 s–1) and with nucleophiles (e.g. with N3–k= 4.2 × 109 dm3 mol–1 s–1 or with water, k 4 × 104 s–1). The radical-cation from 1-naphthylethanoic acid undergoes rapid decarboxylation (k 5 × 105 s–1). The radical cations from 4-methyl- and 4-methoxy-phenylethanoic acid also rapidly decarboxylate to yield the corresponding benzyl radicals.Read More
