40. 6 (0.2 mL) for NMR lock was placed in a 5 mm NMR tube in a glovebox. To the solution was added ferrocenium tetrafluoroborate (13 mg, 0.048 mmol), and the resulting deep-blue solution was degassed by freeze-pump-thaw cycles and sealed. The NMR spectra showed the nearly quantitative formation of 2 as well as the complete disappearance of the signals for 1.
