the 1,2-prototropic route and the decarboxylative route to azomethineylides were studied with cyclopropyl substituents located on one or both carbon atoms of the azomethineylides and in several instances in the dipolarophile. Cycloadducts were obtained in good yield with no evidence of biradical intermediates, i.e. no products arising from cyclopropyl radical ⇀ but-3-enyl radical rearrangements were
