added dropwise to the solution, a TON of 10,510 was reached after 150 h. This is an important
achievement since devising a MeOH reforming system capable of continuously converting
MeOH is of application-wise interest.
The catalytic cycle was suggested to follow the mechanism shown in Figure 12. Initially, the
starting organometallic complex has its hydroxide replaced by a MeOH molecule, which then
undergo β-hydride elimination yielding a formaldehyde molecule, that is extruded, and the
anionic hydride complex. It is not discussed whether an inner- or outer-sphere β-hydride
elimination takes place.
The anionic hydride complex is then prone to protonation at one of the pyridonate moieties,
which affords the neutral hydride complex that then undergoes dehydrogenation resulting
