Does anyone know of a paper where the formal oxidation potential of H2O to O2 in non-aqueous solvents, specially propylene carbonate and acetonitrile, has been measured or estimated?

From my experience, it is difficult to find reliable tabulated data in such a case. The difficulty is that the values will largely vary with the solvent. Furthermore, different sources (authors) have used different reference electrodes and conversion of the data from one to another reference electrode is not easy (no reliable data, again).
Instead, measuring O2 reduction can be simply done by non-degassing the corresponding solvents. You will get the first reduction around -1V vs. AgCl, then you can apply different reference electrodes (NHE, SCE, AgCl, ferrocene).
That will be some work (!), but it will be worth it and MANY colleagues will be very gratefuld if you publish this data. Including me!
