Most interestingly, peroxonitrite does not rearrange to nitrate but decomposes to dioxygen and an O-nitrito complex. 6) [31]. 9) have never been isolated and structurally characterized. Therefore we follow the concept of generating these intermediates within the sterically demanding ligand regime of these guanidine tripod ligands. 6 Modeling copper-monooxygenase C-H hydroxylation and peroxonitrite formation and decomposition. never been detected, different synthetic routes for their synthesis, namely the reactions of [(TMG3tren)Cu]þ , [(DMEG3tren)Cu]þ and [(HPG3tren)Cu]þ with TsN3, [PhI(NTs)]x and [PhIO]x in MeCN, were chosen.

Roth [30], while K. Karlin offered his expertise in well-designed reactivity studies on the superoxo complex. Reactivity is relevant as end-on copper complexes play a role in nature’s enzymatic CH hydroxylation reactions. At the same time, when we proposed the existence of this end-on superoxo complex, Prigge et al. presented an unusual end-on Cu-O2 complex observed in an XRD structure of pepdidylglycine-a-hydroxylating monooxygenase [33] refined to 185 pm. This important finding supports the view that an end-on superoxo mono copper site is the precatalytic species in the a-hydroxylation of CÀH bonds by this enzyme.

Despite the fact that the active coordination site L0 is deeply buried in the center of the molecules, it is readily accessible for a wide range of exogenous guest molecules. A large number of crystal structure determinations have provided insights into the binding modes of the coligands. These sense the size and form of the binding pocket of the [M2L]2 þ fragments, as indicated by distinctive binding modes and unusual conformations. The use of the N-alkylated macrocycles in place of the unmodified analogs influences many properties of the binuclear complexes, including color, molecular and electronic structure, hydrogen bonding interactions, redox potential, complex stability, and ground spin-state.
