applicability of Au>99Ag1NPore was tested for hydrogena‐
M.; Doepp, R.; Anantharaman, S.; Marchetti, B.; Ber‐
tion of a variety of functional groups. Wide ranges of alde‐
hydes including unsaturated aldehydes were reduced to
the corresponding alcohols in high yields with excellent
chemoselectivities. Cis‐semihydrogenation of internal al‐
kynes as well as partial reduction of terminal alkynes were
realized with excellent selectivities. Additionally, the selec‐
tive reduction of terminal alkynes was obtained in the pres‐
ence of internal alkynes, which otherwise could not be
achieved using commercial available supported gold nano‐
particles. In similar manner, the reductive amination
which has great significance in synthesis of amines due to
its atom economical nature has also been realized using
Au>99Ag1NPore. Further, Au>99Ag1NPore/H2 system in tri‐
ethylamine is found to show preference for the reduction
aldehyde in the presence of imine. Apart from this, less re‐
active functional groups such as nitro, quinoline, ketone,
alkene, could also be reduced to the corresponding prod‐
ucts in lower yields.
