of the oxide shell around both Fe CSNPs and C–Fe CSNPs
results directly from the presence of water during their synthesis.
This contrasts with the previously reported examples of Fe NPs,

reagents, or Fe(CO) decomposition. Fe CSNPs were less

active than Fe NPs, but their oxide shell does provide protection
to allow reaction in an aqueous environment and under ligand-
free conditions. Water, as a main poison to a pure Fe(0) surface,
may interact strongly with this shell and migrate more slowly
than the lipophilic substrates. The selectivity of the hydro-
genation of citral (Table 1, entry 9) is of interest. Of the two
available CQC double bonds, the isolated double bond was
converted more quickly than the traditionally more active

an orienting affect of the iron oxide shell—directing the less
polar double bond to the zero valent core, thus leaving the
more polar aldehyde (along with its conjugated partner) to
interact with the oxide shell and polar solvent environment.
We have described the first water-stable catalytic hydro-
genation system based on iron nanoparticles. Specifically, we
have identified iron-iron oxide core–shell nanoparticles as
robust, magnetically recoverable catalysts for hydrogenation
of olefins and alkynes, in ethanol and aqueous ethanol. The
system is active towards many substrates and strictly selective
for alkenes and alkynes over carbonyl and aromatic groups.
These results suggest that the presence of an oxide shell is not
an obstacle to activity and does provide protection against
oxidation by oxygen and water. Commercially prepared particles
were also active, opening an opportunity to apply this reaction
under more realistic conditions.
