Lithium tetramethylpiperidide (LiTMP or harpoon base) Other strong non-nucleophilic bases are sodium hydride and potassium hydride. These compounds are dense, salt-like materials that are insoluble and operate by surface reactions. Some reagents are of high basicity (pK a of conjugate acid around 17) but of modest but not negligible ...

An organic base is an organic compound which acts as a base. Organic bases are usually, but not always, proton acceptors. They usually contain nitrogen atoms, which can easily be protonated. For example, amines or nitrogen-containing heterocyclic compounds have a lone pair of electrons on the nitrogen atom and can thus act as proton acceptors. [1]
1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) is a chemical compound with the formula C 7 H 12 N 2. [1] It is an amidine base used in organic synthesis. A related compound with related functions is 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The relatively complex nature of the formal names for DBU and DBN (hence the common use of acronyms) reflects the ...
It is a strong, non-nucleophilic base. It is flammable and moisture sensitive. It is sometimes written in the chemical literature as sodium t-butoxide. It is similar in reactivity to the more common potassium tert-butoxide. The compound can be produced by treating tert-butyl alcohol with sodium hydride. [3]
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.

As a reagent in organic chemistry, DBU is used as a ligand and base. As a base, protonation occurs at the imine nitrogen. [5] Lewis acids also attach to the same nitrogen. [6] These properties recommend DBU for use as a catalyst, for example as a curing agent for epoxy resins and polyurethane.
