WebFeb 1, 1999 · High selectivity for 1-butene (Hofmann orientation) from 2-butanol is indicative of E1cB, whereas E1 and E2 give mainly 2-butene (Saytzeff orientation). Noller and Thomke [10] recommend the use of deuterated reactants or deuterated catalysts (OD group on the surface of oxide instead of OH groups). WebOrientation in E2: Saytzeff vs Hofmann • Hofmann (working on RNMe 3 + compounds) states that hydrogen will be eliminated preferentially from that β-carbon atom which is attached with most number of hydrogen atoms. Therefore, according to Hofmann rule ‘thatalkene will predominate which has least alkyl substituents on the double bond …
