Nettet- E2 reactions are regioselective and favor the formation of Zaitsev products. ADVANCED ORGANIC CHEMISTRY – I (MPC 102T) UNIT- I: Elimination reactions (E1 & E2; Hoffman & Saytzeff’s rule) NettetBased on this analysis, Zaitsev stated that stable alkene is formed when the removal of hydrogen from β-carbon has a low number of hydrogen substituents. During elimination reactions, Saytzeff’s Rule comes into the picture. The most substituted product would be the most stable and most preferred one.

The Hofmann Elimination reaction follows the Hofmann alkene synthesis rule.
