SOME NOVEL ISOXAZOLE PHOTOCHEMISTRY: A COMPARISON WITH VINYL AZIDE CHEMISTRY
Sauers, Ronald R.,Van Arnum, Susan D.
, p. 5797 - 5800 (1987)
Product profiles from the irradiations of 3-acetyl-5-methylisoxazole (4) and Z-3-azido-3-hexene-2,5-dione (5) were compared.Whereas both compounds gave rise to azirine 7, diacetylacetonitrile (6) was produced only from (4).
