Metal-independent decomposition of hydroperoxides by halogenated quinones: detection and identification of a quinone ketoxy radical.

Proc. Natl. Acad. Sci. U. S. A. 106(28) , 11466-71, (2009)

We have shown recently that halogenated quinones could enhance the decomposition of hydroperoxides and formation of alkoxyl/hydroxyl radicals through a metal-independent mechanism. However, neither th...
