Syntheses of and a rearrangement in tropone–imine systems
Abstract
Tropyl azide (I) can be decomposed to form tropone-imonium azide (III) and N-tropyltroponeimonium azide (II); attempts to convert either salt or the corresponding fluoborates into tropone 2,4-dinitrophenylhydrazone leads to the corresponding benzaldehyde derivative.
