Graphical Abstract
A highly specific and catalytic oxidation of water occurs when using a dinuclear Mn complex of a mononegative carboxylate-containing pentadentate ligand (see scheme). Isotope-labeling experiments coupled with membrane inlet mass spectrometry show that one oxygen atom in the evolved O2 molecule is derived from water and the other from the oxidant.

- 6MIMS is a method that allows the analysis of volatile compounds in liquid media. The only separation between the polar media and the mass spectrometer is a thin polymer film. Volatile and hydrophobic compounds dissolve in the membrane, diffuse through it, and evaporate into the ion source of the mass spectrometer, where they are ionized and analyzed according to their mass-to-charge ratios. The method is highly suited for measuring gases and organic compounds in aqueous media, and enables measurements in the low-ppm range. The response time is only a few seconds, and the method has been used for studies of complex chemical reactions[26] and for online measurements in microbial media.[5] We have attempted to assess the electron-impact mass spectrometry (EIMS) methods used in the analysis of 18O-labelling experiments in references [20, 23, 24]. Unfortunately, insufficient detail was provided (in supplementary information) to describe the experimental protocols. Thus, we assume that the gas in the head space over the reactions was analyzed. This method is fundamentally different to MIMS and is not quantitative.
- 7A deliberate injection of O2 into the system does not invoke this response, rather the surge is recorded, and this immediately decays exponentially.
- 8We are currently designing a new cell so that a continuous supply of TBHP can be added in order to attain a steady state of catalytic activity. Visual inspection of the reactions indicates that the concentrations used in the MIMS experiments are not optimal and the system potentially produces much greater amounts of product.
- 9We have not found determinations of O-exchange between water and tBuOOH in the literature. However, the specific production of one isotopomer observed in our work is indirect evidence that any exchange of this nature is not kinetically relevant. If there was significant exchange then a distribution of isotopes, 16O2, 18O16O, and 18O2, would be observed. Furthermore we have monitored the reaction solution at m/z 92, which corresponds to singly 18O-labeled TBHP. No trace was detected (and we do see unlabeled TBHP at m/z 90). Therefore competing homolytic cleavage of the OO bond in TBHP and consequent radical Haber–Weiss chemistry can be eliminated in mechanistic considerations. Furthermore oxidation is observed with the CeIV oxidant.

- 21The nitrate complex (NH4)2[Ce(NO3)6] is that normally used as a source of CeIV in oxidation reactions. However, participation by the nitrate ion is not normally considered.
- 22As mentioned in the text, the nitrate-containing [MnIII(mcbpen)NO3]+ is in fact observed in the ESI mass spectra of the reaction solutions. This fact cannot be regarded as evidence for Mn activation for nitrate reduction. However, it does suggest a higher concentration of [MnIII(mcbpen)NO3]+ than the isoelectronic [MnIII(mcbpen)OH]+, which is seen in the TBHP reactions. An attempt to verify the possible involvement of nitrate in the water oxidation was made by adding a 100-fold excess of sodium nitrate to the reaction. This resulted in complete inhibition of the reaction. This observation is not surprising if nitrate is capable of substituting the water ligands of 1-2 (ClO4)2 and consequently inhibiting the reaction. We have also attempted to detect the N18O16O2− isotopomer by negative-ion ESIMS. Unfortunately, in the presence of such large excess of the unlabeled nitrate, this experiment was beyond the resolution capabilities of our instrument.
