There’s always some reactions that scientists wish they’d had the chance to do - this is one of mine. How freakin’ awesome is that oxidising species!? How often do people get the chance to party with a hypervalent periodinane!? Exactly.
As a sexy alternative to the Swern oxidation, this reaction also converts primary alcohols into aldehydes (alkanals) or secondary alcohols into ketones (alkanones). This approach however, means no bad smells AND a room temperature reaction :)
That beautiful iodine complex encourages just a mild oxidation. This means no over-oxidising to make some unwanted carboxylic (alkanoic) acid. It’s also easily separated from your product mixture too -everybody wins ^_^
NB. The -Ac is just an acetyl group
