WebAcid chlorides can be converted to aldehydes using a hindered reducing agent such as lithium tri-tert-butoxyaluminum hydride LiAlH (Ot-Bu) 3 or diisobutylaluminum hydride (DIBALH). These hydride sources are weaker reducing agents than lithium aluminum hydride in part because they are sterically hindered. WebAldehydes, RCHO, can be oxidised to carboxylic acids, RCO 2 H. Ketones are not oxidised under these conditions as they lack the critical H for the elimination to occur (see mechanism below). The reactive species in the oxidation is the hydrate formed when the aldehyde reacts with the water.
