Abstract A series of 2-hydroxyaryl ketoximes were converted to the corresponding 1,2-benzisoxazole 2-oxides by treatment with iodobenzene diacetate (in acetic acid or methanol) or N-chlorosuccinimide in water. Both methods gave moderate to excellent yields for a variety of substituted oximes under mild conditions within short reaction times. The latter method has the advantages of an aqueous solvent

Abstract An efficient and convenient methodology has been developed for the conversion of 2-hydroxy phenyl ketoxime to 1,2-benzisoxazole 2-oxide with sodiumperborate (SPB) in glacial acetic acid under mild reaction conditions. Interestingly when the reaction was carried out under reflux condition deoximation was observed in quantitative yield.

Compounds with strong absorptions in the ultraviolet (UV) region of the spectrum, particularly the UVA and UVB, have seen much interest as UV screeners or absorbers in a wide variety of commercial products. A series of benzisoxazole 2‐oxides have been synthesized and characterized by UV–vis spectroscopy. A number of derivatives have been shown to posses moderate to strong molar absorption coefficients
