A quantitative NMR protocol has been developed to study the ruthenium‐ion‐catalyzed oxidation of a range of alkylated polyaromatics, as reported by S. H. Taylor et al. in their Full Paper on page 4285 ff. RuO4 acts as a very selective catalyst, targeting the oxidation of aromatic carbon in preference to aliphatic carbon in alkyl‐substituted polyaromatic hydrocarbons.
Ruthenium‐ion‐catalyzed oxidation of a range of alkylated polyaromatics has been studied. 2‐Ethylnaphthalene was used as a model substrate, and oxidation can be performed in either a conventional biphasic or in a monophasic solvent system. In either case the reaction rates and product selectivity are identical. The reaction products indicate that the aromatic ring system is oxidized in preference...
