- Since all the reactions were carried out in the presence of triethylamine, a possible activation of sulfur by this base (See refs. [13–15]) cannot be responsible for the differences observed
- Albeit the concentration of diphenyl phosphonate anion was still below the detection level of 31P NMR spectroscopy
