As a primary haloalkane, it is prone to S N 2 type reactions. It is commonly used as an alkylating agent. When combined with magnesium metal in dry ether, it gives the corresponding Grignard reagent. Such reagents are used to attach butyl groups to various substrates. 1-Bromobutane is the precursor to n-butyllithium: [4] 2 Li + C 4 H 9 X → C ...
Butyl bromide (C 4 H 9 Br) may refer to: 1-Bromobutane (n-Butyl bromide) 2-Bromobutane (sec-butyl bromide) 1-Bromo-2-methylpropane (isobutyl bromide)
Tetrabutylammonium bromide can be prepared by the alkylation of tributylamine with 1-bromobutane. [2] Tetrabutylammonium bromide is used to prepare other salts of the tetrabutylammonium cation by salt metathesis reactions. [6] It serves as a source of bromide ions for substitution reactions.
While some n-butylpotassium is present and is a stronger base than n-BuLi, the reactivity of the mixture is not exactly the same as isolated n-butylpotassium. [10] An example of the use of n-butyllithium as a base is the addition of an amine to methyl carbonate to form a methyl carbamate, where n-butyllithium serves to deprotonate the amine:

In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
Tetrabutylammonium chloride is the organic compound with the formula [(CH 3 CH 2 CH 2 CH 2) 4 N] + Cl −, often abbreviated as [Bu 4 N]Cl, where Bu stands for n-butyl. A white water-soluble solid, it is a quaternary ammonium salt of chloride. It is a precursor to other tetrabutylammonium salts.
An intramolecular S N 2 reaction by the anion forms the cyclic backbone of morphine. [14] Synthesis of morphine using lithium–halogen exchange. Lithium–halogen exchange is a crucial part of Parham cyclization. [15] In this reaction, an aryl halide (usually iodide or bromide) exchanges with organolithium to form a lithiated arene species.
