Voronenkov, V. V. published the artcileSynthesis of p-alkylbenzoic acids by one-electron oxidation of p-alkyltoluenes. MINDO/3 calculations of p-alkyltoluenes and their radical cations, Application In Synthesis of 20029-52-1, the publication is Zhurnal Organicheskoi Khimii (1989), 25(12), 2565-9, database is CAplus.
The role of σ,π-conjugation in determining the regiochem. of one-electron oxidation of the title compounds, i.e., p-MeC6H4CHMe2, was investigated by MINDO/3 mol.-structure calculation The isopropyl-group C-H bond was in the plane of the aromatic ring, a conformation preventing its participation in σ,π-conjugation; two of the Me-group C-H bonds were perpendicular to the aromatic plane, however, suggesting their participation in σ,π-conjugation could significantly enhance their acidity and deprotonation affinity. Analogous results were obtained for p-cyclopropyltoluene.
