Tetraalkyl-(2)-tetrazenes are attacked by azodicarboxylates at the dialkylamino nitrogen. By intramolecular proton abstraction, the betain 3 first formed is converted into the ylide 4 which then rearranges into 5. Kinetics of the reaction are investigated by UV spectroscopy; a mechanism is proposed.
