1, 8-Diazabicyclo[5.4.0]Undec-7-Ene

1, 8-diazadicyclic [5.4.0] undecane 7-ene referred to as DBU, is a double heterocyclic structure of amidine, colorless or light yellow liquid at room temperature, soluble in water and ethanol, acetone and other organic solvents, generally less than 30℃Chemicalbook storage. As a strong organic base with unique structure, it has been applied in many synthesis reactions, showing the catalytic effect that other strong bases are difficult to play, and has the characteristics of mild reaction conditions, simple synthesis steps, specific product selectivity and high yield.
Nature:
1, appearance and properties: is a colorless, transparent liquid. It has a strong ammonia taste and is highly hygroscopic.
2, solubility: soluble in many common organic solvents, such as ethanol, ether, chloroform and dimethylformamide.
3, stability: It is stable and can be stored for a long time at room temperature.
4, combustibility: it is flammable, pay attention to avoid contact with the fire source.

1, 8-diazadicyclic [5.4.0] undeca-7-ene is an excellent dehydrating agent, epoxy resin hardener, rust inhibitor, and can be formulated as an advanced corrosion inhibitor. A catalyst that can be used for the production of polyaminoethyl ester and other chemicals, such as ammonia and dichloroethane in the presence of a Chemicalbook reaction to produce piperazine. It is widely used in the production of semi-synthetic antibiotics of cephalosporin. It is a resin curing accelerator, especially for the outer sealing resin of integrated circuits and electronic components; Dehalogenation reaction, dimerization and trimer dehalogenation reaction; Desulfonic acid, denitric acid reaction in polymerization process.
Purpose:
1, catalyst: is a strong base, commonly used as a base catalyst in organic synthesis, especially in condensation reaction, substitution reaction and cyclization reaction.
2, ion exchanger: can form salts with organic acids, and used as anion exchangers, often used in organic synthesis and analytical chemistry.
3, chemical reagents: often used in organic synthesis of hydrogenation reaction, deprotection reaction and strong base catalyzed amine substitution reaction.
