Concept explainers
Interpretation:
The structural formula for the compound D and for the product,
Concept introduction:
The
Wittig reaction is a reaction in which a nucleophilic elimination occurs after nucleophilic addition reaction. In this reaction an aldehyde or ketone reacts with a triphenyl phosphonium ylide (Wittig reagent) to give an
The reaction can be represented as shown below,
Mechanism:
It is possible to generate sulphur ylides in a manner similar to that used to produce phosphonium ylides. For example, treating a sulfonium salt with a strong base gives the sulphur ylide.
Sulfur ylides reacts with ketone to give

- Following is the structural formula of the tranquilizer meparfynol (Oblivon). Propose a synthesis for this compound starting with acetylene and a ketone. (Notice the -yn- and -ol in the chemical name of this compound, indicating that it contains alkyne and hydroxyl functional groups.)arrow_forwardNonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.arrow_forwardGrignard reagent is a versatile tool in synthetic organic chemistry. Using bromocyclopentane as a starting material, show how a Grignard reagent, X, is synthesized. Reaction of X with water produces compound Y while treatment in carbon dioxide followed by hydrolysis forms compound Z. 3-methyl-2butanone reacts with X and hydrolyses to yield compound AA. Draw the structural formulae of compounds Y, Z and AA and write the chemical equations respectively.arrow_forward
