Five different 2-pyrrole-1-oxides have been prepared by dehydrogenation of their corresponding pyrroline-1-oxide presursors and characterized by 1,3-dipolar cycloadditions with dimethyl ethyne dicarboxylate and/or N-phenyl maleic imide.

It has been shown for the first time that nitrosation of phenylcyclopropanes with bulky alkyl substituents in the small ring proceeds predominantly with attack of the nitrosonium cation on the benzyl carbon atom of the cyclopropane ring with intermediate formation of an alkyl carbocation. In addition to isoxazolines, 1,2-oxazines and Delta(1)-pyrroline N-oxide are formed, formation of the latter is preceded by skeletal rearrangement.
