As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile.Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions.

It is used as a non-nucleophilic base, being comparable to LiHMDS in terms of steric hindrance. Synthesis It is ...
It is a strong, non-nucleophilic base with an approximate pK a of 26 (compare to lithium diisopropylamide, at 36). [citation needed] Structure.
In a similar implementation, 2,6-lutidine is thus sometimes used in organic synthesis as a sterically hindered mild base. [4] One of the most common uses for 2,6-lutidine is as a non-nucleophilic base in organic synthesis. It takes part in the formation of silyl ethers as shown in multiple studies. [5] [6]
N,N-Diisopropylethylamine, or Hünig's base, is an organic compound that is a tertiary amine. It is named after the German chemist Siegfried Hünig . It is used in organic chemistry as a non-nucleophilic base. It is commonly abbreviated as DIPEA, DIEA, or i-Pr 2 NEt.
TMP is the starting material for an even stronger base, lithium tetramethylpiperidide and the radical species TEMPO. Another non-nucleophilic base is N,N-diisopropylethylamine . Its aqueous p K aH (conjugate acid dissociation constant, a measure of basicity) is 11.07 at 25 °C, [ 1 ] while its p K a (acid dissociation constant, a measure of ...
LDA is a strong, non-nucleophilic base [6] The main commercial applications of diisopropylamine is as a precursor to the herbicide, diallate and triallate as well as certain sulfenamides used in the vulcanization of rubber. [7] It is also used to prepare N,N-diisopropylethylamine (Hünig's base) by alkylation with diethyl sulfate. [8]
