Various alkyl-substituted p-dialkoxybenzenes (ArH) react readily with nitrogendioxide (NO2) in dichloromethane solution via either nitration (ArNO2) or oxidative dealkylation to quinones (Q). Spectral transients indicate that these coupled processes from the dialkoxybenzene radical cation (ArH+·) formed as the common reactive intermediate from electron-transfer in the disproprtionated precursor [ArH
Despite the Lewis acidic character of MoCl5 it can be employed for the selective oxidative coupling reaction of alkylated anisole derivatives without transalkylation or de-tert-butylation of the substrates. The spatial demand close to the donor function seems to be beneficial.
