WebbThe most effective way to cleave alkene is to use ozone, O 3, through a two-step process. Alkene first reacts with ozone at very low temperature (-78°C) and then is treated with dimethyl sulfide (CH 3) 2 S, (or Zn/CH 3 COOH) to give the cleavage products. The whole process is called ozonolysis.
