For recent reviews of elimination reactions see. J.F. Bunnett. Angewandte Chemie (International Ed.), 1 (1962), p. 225. b. D.V. Banthorpe. In organic chemistry, Zaitsev's rule (or Saytzeff's rule, Saytzev's rule) is an empirical rule for predicting the favored alkene product(s) in elimination reactions. While at the University of Kazan, Russian chemist Alexander Zaitsev studied a variety of different elimination reactions and observed a general trend in the resulting alkenes. Based on this trend, Zaitsev proposed that the alkene form…
