The E1 and E2 elimination mechanisms can also be distinguished by a primary deuterium isotope effect, which measures the degree to which C—H and C—D bonds are broken in the rate-determining step.

29/01/2014 · Introduction. Bimolecular base-induced 1,2-elimination (E2) is one of the most elementary reactions in organic chemistry.[1 – 6] Typically, in E2 reactions, an anionic base abstracts a proton from the β-carbon center of a substrate molecule while, simultaneously, a leaving group at the α position is released, as shown in Scheme 1 a. In the broader context of all substitution and elimination reactions, remember that S N 1 and E1 will not occur in the presence of a strong base or a good nucleophile. In these cases, E2 and S N 2 dominate their unimolecular cousins.

In the unimolecular pathway, substitution and elimination share the same slow step: a carbocation intermediate must form. This means that the rate at which substrate is consumed is fixed regardless of what product (elimination or substitution) forms. However, the predominant product of a particular unimolecular reaction
