Abstract
Beckmann rearrangement of acetone oxime, acetophenone oxime and benzophenon e oxime has been studied in the presence of para-toluenesulphonic acid as a solid catalyst. The rearrangement is found to proceed smoothly and under m ilder conditions. It is observed that in the case of benzophenone oxime, el evated temperatures favour rearrangement, while deoximation is predominant at room temperature. An explanation is presented and the mechanism is discu ssed.
