Note: If you haven't come across this reducing agent before, you might find it useful to read a rather more detailed account of its use on the page about reduction of aldehydes and ketones. The present page isn't done in the same sort of detail as that one. Use the BACK button on your browser to return to this page.
Aldehydes are prepared from acid chlorides by reaction with H2 in the presence of palladium catalyst supported on barium sulphate. The catalyst is poisoned by addition of sulphur or quinoline. The poisoning is done to avoid the further reduction of aldehydes to alcohols. This reaction is called Rosenmund's reaction.
The reason for this easy oxidation is the presence of a hydrogen atom on the carbonyl carbon, which can be converted into -OH group without involving the cleavage of any other bond. Thus even weak oxidising agents like bromine water, Ag+, Cu2+ etc are effective. As a result aldehydes act as strong reducing agent.
