WebCleavage of the 1,2 Diol Units t Polyvinyl alcohol is essentially a 1,3 diol polymer: however, the commercial ma- terial contains about 1 to 2 mole percent 1,2 diol units in the molecular structure. Cer- tain oxidizing agents involving divalent reduction such as periodic acid (ref. 7, … WebThe 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. Figure 10.7e The process of Cleavage with Ozone
