Ten millimoles of ethylbenzene were heated at 400° C. for 1 hour with 1.35 ml of water containing 20 millimoles of sodium sulfite and 10 millimoles of lead nitrate. On cooling, a suspension of black precipitate was observed. The reaction product was extracted with ether and the ether layer was dried over Na2SO4 and concentrated to yield acetophenone in more than 95% yield. Acetophenone was confirmed by NMR and gas chromatographic techniques.
