Study Notes
Aldehydes from Acid Chlorides
-
Two methods are presented for converting acid chlorides to aldehydes: lithium tri-t-butoxyaluminum hydride reduction and Rosenmund reduction.
-
Lithium tri-t-butoxyaluminum hydride reduction:
- Uses lithium tri-t-butoxyaluminum hydride ($LiAlH(O-t-Bu)_3$) in ether.
- Reactant: R-C(=O)-Cl (an acid chloride)
- Product: R-C(=O)-H (an aldehyde).
-
Rosenmund reduction:
- Uses hydrogen gas ($H_2$) over palladium ($Pd$) on barium sulfate ($BaSO_4$) as a catalyst.
- Reactant: R-C(=O)-Cl (an acid chloride)
- Product: R-C(=O)-H (an aldehyde).
