Category: Elimination Reactions

Now that we have seen a few examples of elimination reactions, it is time to return to our discussion of the two mechanisms for elimination. To summarize what we have said so far: There are a number of factors that decide whether an elimination goes by an E1 or an E2 mechanism. One is immediately…

Haloforms undergo base-catalyzed α-elimination in two stages, the second of which is rate-determining with the formation of carbenes. The carbanion intermediates owe their stability in part to the ability of all the halogens except fluorine to accommodate the negative charge in d orbitals. The resulting order of reactivity in the first step is CHI3 > CHBr3 >…

Reactions in which a molecule of two atoms or groups is removed from a compound and which are not replaced by other atoms or groups are referred to as elimination. It belongs to one of the important class of organic reactions. The atoms or groups can be bound to carbon atoms and/or to heteroatoms in the…
