Abstract

A drastically enhanced stability is observed for organoazides (RN₃ ) in the presence of Cu²⁺ or Pd²⁺ when the azido group is included in a ligand system chelating the transition metal ions. X-ray structure analysis of such complexes (the structure of a cyclohexaneazide palladium complex is depicted) confirms that the alkylated nitrogen atom of the N₃ moiety is coordinated to the transition metal center.

Keywords: Azides; Copper; Palladium.
