Study Notes
Oxidation and Reduction Reactions
- PCC (Pyridinium Chlorochromate) is used to selectively oxidize primary alcohols to aldehydes.
- The Grignard reagent RMgBr is used to synthesize a ketone from a nitrile, with the correct sequence being: nitrile → imine → ketone.
- DIBAL-H (Diisobutylaluminium Hydride) is used to selectively reduce an ester to an aldehyde.
- Lithium tri-tert-butoxyaluminium hydride (LTBA-H) is used to reduce acid chlorides to aldehydes in organic synthesis.
- The Rosenmund reduction is used to reduce an acid chloride to an aldehyde.
Ketone Synthesis
- The Grignard reagent RMgBr is commonly used to convert a nitrile into a ketone.
- Alkynes can be converted into ketones through hydroboration oxidation followed by reaction with water and hydroxide.
- The synthesis of ketones from nitriles involves the use of Grignard reagents and water.
Aldehyde Synthesis
- The reduction of esters using DIBAL-H is a common method for the synthesis of aldehydes.
- PCC can be used to convert secondary alcohols into ketones.
Reaction Types
- Nucleophilic addition is a type of reaction that involves nucleophiles attacking aldehydes or ketones.
Acid Chloride Reactions
- The reaction of an acid chloride with a primary alcohol forms an ester.
