Herein we report a two-step sequence for the preparation of amides starting from azides and enolisable aldehydes. The reaction proceeded via the formation of triazoline intermediates that were converted into amides via Lewis acid catalysis. Preliminary st

Aryl-substituted ketene imines (1a-1i) have been studied both in dichloromethane and acetonitrile by cyclic voltammetry. In addition to the multi-annulated heterocycles products of type 2-4 previously obtained by ketene imines 1a-1d, the anodic oxidation of ketene imines containing electron-withdrawing substituents and electron-donating substituents at the ortho position, affords also monocyclic dimers of type 5 (from 1e-1f) and of type 6 (from 1h-1i). The results are discussed in terms of both electronic and steric effects.
