Abstract:
Mono-, bis-, and tris-1,2,3-triazole ligands are used for the stabilization of gold nanoparticles (AuNPs), and the catalytic activities of these AuNPs in 4-nitrophenol reduction by NaBH4 in water are compared as well as with polyethylene glycol 2000 (PEG)- and polyvinylpyrrolidone (PVP)-stabilized AuNPs. The excellent catalytic results specifically obtained with the tris-triazolate ligand terminated by a PEG tail are taken into account by the synergy between the weakness of the tris-triazole-AuNP bond combined with the stabilizing ligand bulk.

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...
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.
