Fig. 3. (A) Intermediates and side products in the phosphorylation of pyruvate to PEP with P4O10. (B) Typical 1H NMR spectrum (H2O/D2O 9 : 1 mixture, 400 MHz) of the quenched reaction mixture after 3 min at 60 °C. (C) Qualitative evolution of the main species in the reaction (for details, see Table S5 and p. S24†).
