Description

Description générale

N,N-Diisopropylethylamine (DIPEA), also known as Hunig′s base, is a sterically hindered amine. It is a non-nucleophilic base commonly employed in substitution reactions, alkylations, and amide couplings, etc. DIPEA is also used as a base in the Pd catalyzed cross-coupling reactions, which include Heck coupling and Sonagashira coupling reactions.

Application

• Catalytic activity in dioxygen reduction: A study utilized Mn complexes with pendent proton donor relays and added base, including N-Ethyldiisopropylamine, to control product selectivity during dioxygen reduction, providing insights into catalytic mechanisms and potential industrial applications (Cook et al., 2024).


• Three-dimensional imaging in medical applications: N-Ethyldiisopropylamine was mentioned in the context of its role in improving the resolution of three-dimensional imaging techniques based on computed tomography angiography (CTA), crucial for preoperative perforator selection in reconstructive surgery (Su et al., 2024).


• Synthesis of Spirocyclopropane-Containing Compounds: Research demonstrated the application of N-Ethyldiisopropylamine in the synthesis of spirocyclopropane-containing 4H-pyrazolo[1,5-a]indoles through alkylative dearomatization and intramolecular N-imination, highlighting its utility in complex organic synthesis (Huang et al., 2023).
