Draw all steroisomers formed in the reaction below.
Wittig reaction that forms alkenes from aldehyde or ketone using ylides. This reaction is a condensation reaction. Thus, it is a good synthetic reaction producing larger compounds. Also, the double bond only forms on the carbonyl carbon replacing the carbon-oxygen double bond does alkene formation is quite specific. The only side products are the stereoisomers of the alkene since both isomers can be formed.
Answer and Explanation:
All products are shown below:
This reaction is called the Wittig reaction. It forms alkenes from carbonyl compounds(ketone or aldehyde) with ylides. Ylides are organophosphorus reagents that can act as a nucleophile. This reaction is a three-step reaction where the ylide attacks the carbonyl carbon followed by the formation of a 4-membered ring and lastly the formation of the alkene. Both Z and E alkene isomers can be formed from this reaction.
