Description

General description

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, 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.
