Alkyl halides may undergo elimination reactions with BrØnstead-Lowry bases in which the halide and an adjacent proton are lost to form a new π bond. Because of the loss of a proton and a halide anion the reactions are termed ‘dehydrohalogenation’. The two most common associated mechanisms are designated as either unimolecular (E1) or bimolecular (E2) elimination reactions based on reaction rate studies. E1 reactions proceed via a two-step mechanism that involves the cleavage of the leaving group (here the...
