General description
2-Bromobutane is an alkyl halide. Degradation of 2-bromobutane by reductive dehalogenation in the presence of nickel-aluminum alloy in potassium hydroxide solution has been reported. Gas chromatographic determination of 2-bromobutane in mixture of alkyl bromides has been reported. Stereochemistry of dehydrobromination of 2-bromobutane over KOH-silica has been investigated.
Viscosities of binary mixtures of 2-bromobutane and the isomeric forms of butanol have been evaluated at 298.15 and 313.15K. 2,2-dibromobutane, meso-2,3-dibromobutane and dl-2,3-dibromobutane are formed as major photobromination reaction products, during its reaction with molecular bromine. Smaller yields of 1,2-dibromobutane and 2,2,3-tribromobutane are also obtained in this reaction.
Application
2-Bromobutane may be used in the synthesis of series of non-nucleosides.
