Heterogeneous catalysis with nickel-on-graphite (Ni/Cg): Reduction of aryl tosylates and mesylates

(Chemical Equation Presented) How would you reduce an aryl OH group? Traditionally, a palladium catalyst, a mild source of hydride, and a triflate derivative are used in solution. A more modern alternative is presented that is not only economical but heterogeneous as well. Nickel-on-graphite (Ni/C g) is introduced as a very inexpensive catalyst that reduces aryl tosylates and mesylates with excellent functional group tolerance.
