The description of N,N-Diisopropylethylamine

N,N-Diisopropylethylamine, or Hünig's base, DIPEA or DIEA, is an amoebic admixture and an amine. It is acclimated in amoebic allure as a base. Because the nitrogen atom is cloistral by the two isopropyl groups and an ethyl accumulation alone a proton is baby abundant to calmly fit. Just like 2,2,6,6-tetramethylpiperidine, this admixture is a acceptable abject but a poor nucleophile, which makes it a advantageous amoebic reagent. Hünig's abject is alleged afterwards the German chemist Siegfried Hünig.Hünig's abject is commercially available. It is commonly able by the acknowledgment of diisopropylamine with diethyl sulfate.Hünig's abject was advised for its use as a careful reagent in the alkylation of accessory amines to tertiary amines by alkyl halides. This amoebic acknowledgment is generally bedfast by a quaternization acknowledgment to the quaternary ammonium alkali but this side-reaction is absent if Hünig's abject is present.Hünig's abject forms a circuitous heterocyclic admixture alleged scorpionine by a acknowledgment with disulfur dichloride catalyzed by DABCO in a arresting one-pot synthesis.N, N-Diisopropylethylamine, or Hünig's base, DIPEA or DIEA, is an amoebic admixture and an amine.
