The oxidation of an aldehyde produces a n
Aldehydes participate in many reactions. From the industrial perspective, important reactions are (a) condensations, e.g., to prepare plasticizers and polyols, and (b) reduction to produce alcohols, especially "oxo-alcohols". From the biological perspective, the key reactions involve addition of nucleophiles to the formyl carbon in the formation of imines (oxidative deamination) and hemiacetals (structures of aldose sugars). Webb-Oxidation of alcohols is usually done under acidic or basic conditions to facilitate electron transfer. b-PCC will not oxidize an aldehyde to a carboxylic acid. -All alcohols can be oxidized to form one of an aldehyde, ketone, or carboxylic acid.
