1,3-Dipolar Cycloaddition of Dipolar Reagents to Bifunctional Olefins in the Presence of Chloramine-T (CAT)
Abstract
2-Pyrazolines and 2-isoxazolines are prepared by the reaction of araldehyde hydrazones and araldoximes with bifunctional olefins in the presence of chloramine-T, which also functions as a reagent for aromatization of the former.
