Wittig Reaction Mechanism

  1. Dec 4, 2013 #1
    Can anyone please walk me through the mechanism as this question does not make sense to me. I do have some understanding of the general mechanism. The answer is B) but I don't understand how to get there.

    The confusing aspect to me, is the structure of the ylide.

    How do you know the answer is B? Is that your guess or did you just get the answer from someone/somewhere? Why wouldn't it be D, for example?

    You say you know how the Wittig reaction works, can you go through the mechanism with these particular reagents? Maybe we should start out with this: what is the first step of the mechanism? What makes the Wittig reagent so useful?

    Also this belongs in the HW section because it's clearly some type of School type question.
