Example of saytzeff rule

WebAlexander Zaitsev (also pronounced as Saytzeff) who in 1875 formulated a rule which can be summarised as “In dehydrohalogenation reactions, the preferred product is that alkene which has the greater number of alkyl groups attached to the doubly bonded carbon atoms.” Thus, 2-bromopentane gives pent-2-ene as the major product. WebZaitsev's Rule can be used to predict the regiochemistry of elimination reactions. Zaitsev’s or Saytzev’s (anglicized spelling) rule is an empirical rule used to predict regioselectivity of beta-elimination reactions occurring via the E1 or E2 mechanisms. It states that in a regioselective E1 or E2 reaction the major product is the more ...
