1. Catalyst: DBN can be used as a non-precious metal catalyst to promote various organic reactions, such as esterification, acylation, alcohol esterification, halogenation reaction, amination reaction, etc. Its alkalinity can neutralize the acidic effect produced by the acid catalyst and provide an alkaline site to facilitate the reaction.

2. Ligands: chemical 1,5-diazabicyclo[4,3,0] king ene-5 (DBN) can form coordination bonds and coordination complexes with transition metals. It is able to provide nitrogen atoms as coordination sites and form stable complexes with metal ions. These complexes play an important role in organometallic catalyzed reactions.

3. Organic synthesis intermediates: DBN can be used as an intermediate in organic synthesis and participate in the synthetic steps of building complex organic molecules. It can be used as a "protective agent" or "activator" of amino groups and plays an important role in various organic reactions.

4. Ionic liquid: DBN can also form ionic liquid with some acids, which has special chemical properties and application potential. These ionic liquids have a wide range of applications in catalysis, solvent and separation.
