The Hofmann Elimination. Amines can participate in E2 reactions to form alkenes. However, just like the OH group of alcohols, the NH 2, or any other amino group, is a quite strong base and needs to be first converted into a good leaving group. This is achieved by methylation of the nitrogen with excess of methyl iodide.

Kumada Coupling Reaction 13m. Negishi Coupling Reaction 16m. Buchwald-Hartwig Amination Reaction 19m. Eglinton Reaction 17m. For each reaction, decide whether substitution or elimination (or both) is possible, and predict the products you expect. Label the major products. a. 1−bromo−1−methylcyclohexane + NaOH in acetone.

Zaitsev’s rule is an empirical rule used to predict the major products of elimination reactions. It states that in an elimination reaction the major product is the more stable alkene with the more highly substituted double bond. This situation is illustrated by the 2-bromobutane and 2-bromo-2,3-dimethylbutane elimination examples given below.

Unlike what happens in other E2 reactions, the major product of Hofmann elimination is the less highly substituted alkene rather than the more highly substituted one, as shown by the reaction of (1-methylbutyl)trimethylammonium hydroxide to give 1-pentene rather than the alternative 2-pentene.
