Abstract
Alkenediols are produced by hydrolysis of a dibromoalkenes in the presence of alkali metal formate. In a preferred embodiment, alkenediols, and particularly 2-butene-1,4-diol, are produced in a series of steps comprising bromination of conjugated diene with cupric bromide, hydrolysis of the resulting dibromobutenes to alkenediols in the presence of alkali metal formate, and regeneration of cupric bromide and alkali metal formate such that only conjugated diene, oxygen and water are consumed.
