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
