This … WebThese elimination reactions proceed through a concerted retro-ene mechanism. (The mechanism is sometimes called Ei.) The thermal elimination of acetic acid from alkyl acetates and the elimination of RSCOSH from alkyl xanthates (the Chugaev reaction) are retro-ene reactions. Retro-ene reactions are partly driven by the gain in entropy.
WebCHUGAEV ELIMINATION REACTION Mechanism: The Chugaev reaction is an intramolecular syn elimination (Ei), and it proceeds through a six-membered transition state involving a cis-β-hydrogen atom of the alcohol moiety and the thione sulfur atom of the xanthate.
