supporting information; experimental part, p. 2460 - 2463 (2010/07/05)
A copper-catalyzed methodology to functionalize remote sp3 C-H bonds in alkyl hydroperoxides is presented. The atom-transfer chlorination utilizes simple ammonium chloride salts as the chlorine source, and the internal redox process requires no external redox reagents.
