Several reaction mechanisms exist for organic reductions:
Direct electron transfer in one-electron reduction with the Birch reduction as example
Hydride transfer in reductions with for example Lithium aluminium hydride
Hydrogen reductions with a catalyst such as the Lindlar catalyst or the Adkins catalyst.
Disproportionation reaction such as the Cannizzaro reaction
Reductions that do not fit in any reduction reaction mechanism and in which just the change in oxidatio ...
