Abstract:
A protocol based on [Ru III (Me 3 tacn)(CF 3 CO 2 ) 2 (H 2 O)]CF 3 CO 2 (1, Me 3 tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane) as catalyst and tert-butyl hydroperoxide (TBHP) as oxidant was developed for oxidation of anisoles to p-benzoquinone monoketals. This reaction can be formally considered as regioselective aromatic C-H oxidation. With 2-methoxyanisole as substrate, 3,4-dimethoxy-4-tert-butoxy-2,5-cyclohexadienone can be obtained in up to 82% yield based on 84% substrate conversion.Key words: oxidation, quinones, tert-butyl hydroperoxide, ruthenium catalyst.
