WebStage 1: The E- selective Wittig reaction requires stabilised ylids whereby the substituents on the carbon are conjugating or anion stabilising, such as a carbonyl group. The mechanism for the formation of this ylid has been omitted here as these molecules are stable enough to be considered starting materials. Stage 2: E- Selective Wittig Reaction.
