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]

It is a colorless liquid with a pleasant odor. Because the carbon atom connected to the bromine is connected to two other carbons the molecule is referred to as a secondary alkyl halide. 2-Bromobutane is chiral and thus can be obtained as either of two enantiomers designated as (R)-(−)-2-bromobutane and (S)-(+)-2-bromobutane.
tert-Butyl bromide used to study the massive deadenylation of adenine based-nucleosides induced by halogenated alkanes (alkyl halides) under physiological conditions. 2-Bromo-2-methylpropane causes the massive deguanylation of guanine based-nucleosides and massive deadenylation of adenine based-nucleosides.
Short-chain alkyl halides are often carcinogenic. The bromine atom is at the secondary position, which allows the molecule to undergo dehydrohalogenation easily to give propene , which escapes as a gas and can rupture closed reaction vessels.
In order for the S N 2 reaction to take place there must be a good leaving group which is strongly electronegative, commonly a halide. [4] In the Williamson ether reaction there is an alkoxide ion (RO −) which acts as the nucleophile, attacking the electrophilic carbon with the leaving group, which in most cases is an alkyl tosylate or an ...
Haloalkane or alkyl halides are the compounds which have the general formula "RX" where R is an alkyl or substituted alkyl group and X is a halogen (F, Cl, Br, I). Haloalkanes have been known for centuries. Chloroethane was produced in the 15th century. The systematic synthesis of such compounds developed in the 19th century in step with the ...
With primary and secondary alcohols, the halide reacts in a S N 2 process forming the alkyl halide 8 and triphenylphosphine oxide. Tertiary alcohols form the products 6 and 7 via a S N 1 mechanism. The driving force behind this and similar reactions is the formation of the strong PO double bond. [9]
