WebSep 24, 2024 · 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. 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).
