CHEM 343: REDOX REACTIONS CHAPTER 20
Aldehyde/Ketone + Raney Nickel --->
|
Corresponding alcohol 1o for aldehydes 2o for ketones
|
Aldo-Keto containing compound + NaBH4
|
Keto-alcohol containing compound Aldehyde more reactive against sodium borohydride
|
Aldo-Keto containing compound + NaBH4/CeCl3 in H2O/EtOH -->
|
Aldo-alcohol containing compound Selectively targets ketone through temporary aldehyde protection
|
1o alcohol + PCC in DCM -->
|
Aldehyde Non acidic conditions prevent side reactions
|
Aldehyde + mCPBA -->
|
Ester product Which group becomes part of the ester depends on migration speed: H>3oalkyl>2oalkyl=phenyl>1oalkyl>methyl
|
Aldehyde + mCPBA -->
|
Carboxylic acid
|
Alkene + mCPBA -->
|
Epoxide This reaction is chemoselective: more nucleophilic alkenes react first Stereochemistry is retained, and it can create a racemic product
|
1o alcohol + H2CrO4 -->
|
Aldehyde initially, but continually oxidation produces a carboxylic acid end product
