Entry M0125    1.10.3.1    catechol oxidase

Previous Step     Next Step

Step 04

The anionic oxygen of the peroxide group deprotonates the second molecule of benzene-1,2-diol, which causes a hydride to be eliminated from the second phenol group, and cleaved of the peroxo bond. The second Cu(I) centre donates a single electron to the second phenol group.
