E1 Elimination reaction: Mechanism, Examples & Stereochemistry

WebE1 reaction is a type of elimination reaction in organic compounds. A beta-hydrogen and a leaving group attached to two adjacent carbon atoms are removed from a compound (substrate) to form a double bond. The removal usually takes place in two steps in the presence of a Lewis base or acid, resulting in an alkene. WebUnimolecular elimination reaction (E1) occurs in two steps: ionisation and deprotonation. During the ionisation bond between carbon and halogen breaks, an intermediate carbocation is formed. During deprotonation, a proton is lost from carbocation. The base further forms a pi bond within the molecule.
