Simple 2-vinylaziridines rearrange on heating to 3-pyrrolines. This newrearrangement is structurally analogous to that of vinylcyclopropanes to cyclopentenes but occurs under much milder conditions, probably by a similar homolytic mechanism via a more stable, allylic-hydrazino-diradical. Thermolysis of a more highly methylated vinylaziridine is complex, however, and depends critically upon the pH
