Abstract:
The selective hydro-deoxygenation of phenols to arenes is of importance for upgrading lignin-derived oxygenates to value-added aromatic chemicals. Here, we report aluminum metaphosphate-supported Pt nanoparticles (Pt/Al(PO3)3) for selective transfer hydrogenolysis of phenols to arenes using cyclic alkanes as the hydrogen source under mild conditions (as low as 150 °C). In addition to substituted phenols, the present catalyst system can also be applied to a substituted catechol or guaiacol.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
