Web12 nov. 2010 · Cytochrome P450 enzymes are responsible for the phase I metabolism of approximately 75% of known pharmaceuticals. P450s perform this and other important biological functions through the controlled activation of C-H bonds. Here, we report the spectroscopic and kinetic characterization of the long-sought principal intermediate … Webfrom the mixture of 1 and m-CPBA (Figure 3). ESI-MS analysis of pure 2 showed a peak at m/Z = 696, corresponding to a [2]+ ion, which was also observed in the 1 + m-CPBA mixture (Figure S4). The same product (2, [NiIII(OCOC 6H 4Cl)(L)]) was thus acquired from the one-electron oxidation of 3, as from the reaction of 1 with excess m-CPBA.
