1,2-Benzisoxazole 2-oxides are prepared by the oxidative cyclisation of o-acylphenol oximes, using either lead(IV) acetate or sodium hypochlorite.The scope and limitations of the reaction are discussed.

EFFETS MICELLAIRES SUR LA BASICITE ET LA REACTIVITE DE NUCLEOPHILES α AROMATIQUES
The oximation of p-nitrophenylacetate by benzaldoximates in aqueous solution is catalyzed by CTAB micelles.The catalysis is more effective when the base strength of the oximate decreases; the reactivity of benzaldoximates is not dependent on their basicity.Our data may be interpreted in terms of orbital-controlled reactions, with interactions between both the n and ? occupied orbitals of the oximates and the LUMO of the acetate.
