The reactions of five cyclopropyl ketones and two 1-phenylcyclopropyl ketones with equivalent amounts of hydrazoic acid have given mixtures of amides. The products resulting from migration of the cyclopropyl group were N-cyclopropylamides; no isomerization to ethylenic or heterocyclic derivatives could be detected. The relative migrations of the groups in the unsymmetrical ketones differ from those predicted from steric considerations; ...
