Marine living beings, plants, animals and human body all contain dimethyl sulfone.

The dimerization reaction of reduced radical is supposed to be the rate determining step and the slower dimerization rate in PC rather than that in EC cause the anomalous decomposition of PC.

还原出来的自由基的二次聚合反应，被认为是这一速率的决定因素。

In addition, it was presumed that the dimerization reaction was attributed to the metal hydride mechanism, and some indirect evidences were obtained for supporting this mechanism.

另外，还讨论了反应的金属氢化物机理，并获得了支持该机理存在的间接证据。
