internal elimination to form a transitory N-ethylbenzoketoketenimine. Alternative pathways involving benzoisoxazolines have been excluded by kinetic evidence and by study of the model substance, 2-ethylbenzo-4-isoxazoline. A competition study has shown that the intermediate benzoketoketenimine exhibits high selectivity in many of its combination reactions, and that for aqueous aceticacid in the pH
