Olefins and diolefins, such as 1,3-butiadiene, may be produced by a method utilizing a series of bromination and dehydrobromination reactions. Bromine may be reacted with n-butane to form dibromobutane. The dibromobutanes may be dehydrobrominating to form 1,3-butadiene. The method may include reacting butene with bromine to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with hydrogen bromide in the presence of oxygen to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with bromine to form dibromobutanes, and dehydrobrominating the dibromobutanes to form 1,3-butadiene.
