Strong oxidation of alcohols
WebThe mechanism involves the rapid protonation of the alcohol to form an oxonium ion, Loss of water would generate an unstable 1° carbocation (BAD!). If a 1° carbocation can become more stable by rearranging, it will. A CH₃ group on C-2 will migrate to C-1 and leave the positive charge on C-2, which is now a 3° carbocation (GOOD!). WebAlcohol oxidation is a class of organic reactions in which the alcohol functional group is converted into another functional group (e.g., aldehyde, ketone, carboxylic acid) in which carbon carries a higher oxidation state.. Through a variety of mechanisms, the removal of a hydride equivalent converts a primary or secondary alcohol to an aldehyde or ketone, …
