CAS: 5162-44-7

4-Bromo-1-butene is a colorless liquid with a boiling point of 102°C. It is soluble in ethanol, acetone, and chloroform. 4-Bromo-1-butene undergoes an acid-catalyzed phase transition to the solid form at temperatures below its melting point. 4-Bromobutene can be synthesized by reacting ethyl bromide with 1-butene in the presence of a catalyst such as copper or silver oxide. The kinetic energy of the reaction is determined by measuring the rate of evolution of hydrogen bromide gas from the reaction mixture. The β-unsaturated ketone reacts with dimethyl fumarate in the presence of sodium hydroxide to produce 4-bromobutene and 2,2'-difluoroethanol. This product has been shown to have IR spectra similar to those for other products containing a hydroxyl group such as phenol and
