Abstract
A new preparation of 1-arylpyrazolidinones, not involving the prior preparation of arylhydrazines , is reported. The reaction of 3-arylaminopropiono hydroxamic acids with chloroformates gives the title compounds. This transformation is discussed in terms of the intermediacy of the corresponding l,4,2-dioxazol-5-one ring system. These intermediates undergo mild nitrogen-atom induced decomposition with simultaneous N-N bond formation. The effects of chloroformates and aryl substitution is discussed.
