Hunig’s base是什么

N,N-Diisopropylethylamine, or Hünig's base, DIPEA or DIEA, is an organic compound and an amine. It is used in organic chemistry as a base. Because the nitrogen atom is shielded by the two isopropyl groups and an ethyl group only a proton is small enough to easily fit. Just like 2,2,6,6-tetramethylpiperidine, this compound is a good base but a poor nucleophile which makes it a useful organic reagent.

Hünig's base forms a complex heterocyclic compound called Scorpionine by a reaction with disulfur dichloride catalyzed by DABCO in a remarkable one-pot synthesis.[1]
