Abstract

The superoxo complex Cr-aq((OO)-O-18-O-18)(2+) reacts with (CH3)(3)C(O)(OO center dot)-O-16-O-16 to generate quantitative yields of mixed-label dioxygen, (OO)-O-18-O-16, demonstrating that this cross-reaction involves head-to-head interaction between the metal-activated and alkyl-activated dioxygen.
