how to Synthesis 5-Bromo-1-pentene?
(1)5-Bromo-1-pentene can be prepared by reacting 4-penten-1-ol with tetrabromocarbon in the presence of triphenylphosphine, and the brominating agent required for the reaction can also be selected as phosphorus tribromide
(2) Low priced 1,5-dibromopentane can also be used as the starting material for the reaction. Under heating, 1,5-dimethylpentane reacts with hexamethylphosphoramide to obtain 5-bromo-1-pentene.
(3) 1,5-dimethylpentane can also be converted to 5-bromo-1-pentene under the action of strong bases such as potassium tert butoxide.
