The Wittig reaction involves coupling between a phosphonium ylide and a carbonyl-containing molecule. If a chemist wants to use the Wittig reaction to synthesize xene, which reactants should be used? Use the graded interactive module below to explore the reactivity and mechanism of the Wittig reaction and to construct the target product molecule. Click and drag a reactant molecule from each column onto the reaction stage. Note the mechanism of the reaction and the obtained products. After constructing...
