1-Bromobutane is the precursor to n-butyllithium: [4] 2 Li + C 4 H 9 X → C 4 H 9 Li + LiX where X = Cl, Br. The lithium for this reaction contains 1-3% sodium. When bromobutane is the precursor, the product is a homogeneous solution, consisting of a mixed cluster containing both LiBr and LiBu.
Mercuric oxide and bromine convert 3-chlorocyclobutanecarboxylic acid to 1-bromo-3-chlorocyclobutane. This is known as Cristol-Firth modification. This is known as Cristol-Firth modification. [ 14 ] [ 15 ] [ 16 ] The 1,3-dihalocyclobutanes were key precursors to propellanes . [ 17 ]
All three have been synthesized by various routes: 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction [1]; 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed]
In the cases of 1,3-, 1,4-, 1,5-, and 1,6- dihalides, Wurtz-reaction conditions lead to formation of cyclic products, although yields are variable. Under Wurtz conditions, vicinal dihalides yield alkenes, whereas geminal dihalides convert to alkynes. Bicyclobutane was prepared this way from 1-bromo-3-chlorocyclobutane in 95% yield. The reaction ...

A space heater sold on Amazon is being recalled due to the potential to cause an "electric shock," resulting in a fire hazard, the U.S. Consumer Product Safety Commission (CPSC) announced Thursday ...
2-Bromo-1-chloropropane, C 3 H 6 BrCl, is an alkyl halide. This simple compound has a chiral center and is used sometimes to determine the enantiomeric resolution of simple chromatographic methods. References
