Abstract

The Huisgen zwitterion, generated from triphenylphosphine and dialkyl azodicarboxylates, afforded upon reaction with diaryl ketones both mono- and bis(alkoxycarbonyl)hydrazones, depending on the reaction conditions.

Key words

Huisgen zwitterion - diaryl ketones - azo compounds - esters - hydrazones
