24. 3OD as solvent.
25. 2, is appropriate.
26. 2- in Equation (2), which was not detected by ESI-MS. may react with further MeOH to establish a new equilibrium.
27. OMe‡ shown in Scheme 1 are appropriate.
28. Scan range: 674.9-705.1, 794.9-825.1, and 936.9-967.1 amu (atomic mass unit); step size: 0.2 amu; dwell time per step: 0.001 s; scan time: 0.47 s. The envelope of the molecular ion of 3 at m/z 1677 was not selected in the rapid scanning experiments because the intensity was too weak.
29. im is essential.
30. The spectrum after 18 s of reaction is essentially identical to that of 3 (Figure 1b).
