Study Notes
Conversions of Organic Compounds
-
Propanone to Propene
- Use a dehydration reaction with an acid catalyst to eliminate water from propanone, forming propene.
-
Benzoic acid to Benzaldehyde
- Convert benzoic acid to benzaldehyde via reduction using lithium aluminum hydride (LiAlH4) or another reducing agent.
-
Ethanol to 3-Hydroxybutanal
- Perform an aldol condensation by reacting ethanol with acrolein or propanal, followed by further reduction if necessary.
-
Benzene to m-Nitroacetophenone
- Nitration of benzene to form nitrobenzene, followed by Friedel-Crafts acylation with acetic anhydride or acetyl chloride.
-
Benzaldehyde to Benzophenone
- React benzaldehyde with phenyl magnesium bromide (Grignard reagent) to introduce a phenyl group, forming benzophenone after hydrolysis.
-
Bromobenzene to 1-Phenylethanol
- Use a Grignard reaction with ethylene oxide, allowing bromobenzene to react and yield 1-phenylethanol upon hydrolysis.
-
Benzaldehyde to 3-Phenylpropan-1-ol
- Conduct a reaction with appropriate Grignard reagent (like phenyl magnesium bromide) followed by acid-catalyzed hydrolysis.
-
Benzaldehyde to α-Hydroxyphenylacetic acid
- Convert benzaldehyde into α-hydroxy ketone through a reaction with hydrocyanic acid followed by acidic hydrolysis.
-
Benzoic acid to m-Nitrobenzyl alcohol
- Perform nitration to generate m-nitrobenzoic acid, then reduce the acid to m-nitrobenzyl alcohol with LiAlH4 or a similar reducing agent.
