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, 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.

A high-performance liquid chromatographic method is presented for the determination of urinary acylcarnitines. After solid phase extraction on silica columns the acylcarnitines are converted to 4'-bromophenacyl esters with 4'-bromophenacylbromide in the presence of N,N-diisopropylethylamine. Complete derivatization was achieved at 37
