Organic superbases are mostly charge-neutral, nitrogen containing species, where nitrogen act as a proton acceptor. These include the phosphazenes, phosphanes , amidines, and guanidines. Other organic compounds that meet the physicochemical or structural definitions of 'superbase' include proton chelators like the aromatic proton sponges and ...
In Organic Chemistry, superacids are used as a means of protonating alkanes to promote the use of carbocations in situ during reactions. The resulting carbocations are of much use in organic synthesis of numerous organic compounds, the high acidity of the superacids helps to stabilize the highly reactive and unstable carbocations for future ...
United Natural Foods, Inc. (UNFI) is a Providence, Rhode Island–based natural and organic food company. The largest publicly traded wholesale distributor of health and specialty food in the United States and Canada, [3] [4] it is Whole Foods Market's main supplier, with their traffic making up over a third of its revenue in 2018.
In chemistry, the Verkade base (or Verkade superbase) is a powerful superbase with the formula P(MeNCH 2 CH 2) 3 N. A colorless oil, it is an aminophosphine although its inventor John Verkade called it proazaphosphatrane.
Most organic bases are considered to be weak.Many factors can affect the strength of the compounds. One such factor is the inductive effect.A simple explanation of the term would state that electropositive atoms (such as carbon groups) attached in close proximity to the potential proton acceptor have an "electron-releasing" effect, such that the positive charge acquired by the proton acceptor ...

Glass bottles containing butyllithium. n-Butyllithium C 4 H 9 Li (abbreviated n-BuLi) is an organolithium reagent.It is widely used as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS).
Bases of carbon, nitrogen and oxygen without resonance stabilization are usually very strong, or superbases, which cannot exist in a water solution due to the acidity of water. Resonance stabilization, however, enables weaker bases such as carboxylates; for example, sodium acetate is a weak base .
