A research investigation into the synthesis of 1, 4‐diazabicyclo[2.2.2]octane from ethylendiamine over zeolite ZSM‐5 was carried out. A number of side products such as alkylpyrazines, alkylpiperazines and alkyl‐1, 4‐diazabicyclo[2.2.2.]octanes were identified in the reaction mixture. A chemical mechanism based on elimination, condensation, cracking and proton transfer reactions was proposed for the formation of these compounds.
