Strong Oxidative Cleavage

When you react a double bond with potassium permanganate (KMnO4), your first thought may be to make syn-diols, as seen in pervious videos. However, looking at the temperature is extremely important. In heat, KMnO4 will actually cleave the double bond, rather than add diols. Let’s check it out. 

Problem: Predict the product of the following reaction.
