the binding energy of PdO, which was 336.1 eV.

According to the characterization results, we can hypothesize
that the hydrogen-borrowing process might be realized through
the cycle between ‘PdO2’ and ‘PdO’ or ‘PdO’ and ‘Pd’. Thus, it was
further investigated by DFT calculations using GAUSSIAN 03 software
(B3LYP/LANL2DZ).21 Undoubtedly, for the two cycles, they all start
from the oxidation of alcohol to form the aldehyde.22 In the mean-
while, the palladium was transferred into ‘PdO’/H2O or ‘Pd’/H2O.
Next, the active palladium species (I) or (II) would be generated
by the reaction of ‘PdO’ or ‘Pd’ with H2O. According to the calibra-

tion, it could be seen that the
DG of Pd(0) + H2O to form species (I)
is +25.08 kcal/mol, which indicates that the formation of active
palladium species (I) for the next step is rather difficult and the
catalytic cycle between ‘PdO’ and ‘Pd’ is blocked. The
DG of
‘PdO’ + H2O to species (II) is +7.78 kcal/mol and thus the formation
of active palladium species (II) is more reasonable, Scheme 2.
On the basis of the above experimental and DFT calculation re-
sults, a possible mechanism for ‘PdO2’ and ‘PdO’ catalyzed N-alkyl-
ation of amines with alcohols is illustrated in Scheme 3. The first
step of the reaction would involve the oxidation of an alcohol to
the corresponding carbonyl compound, with the generation of a
‘PdO’ species (step a). The carbonyl intermediate would readily re-
act with amine to afford an imine (step b). On the other hand, a
reversible cycle between ‘PdO’ and compound (II) was happened
(step c). We propose that the step is a reversible dis-proportiona-
tion of the Pd catalyst, which enters the catalytic cycle as the active
intermediate with a free energy cost of +7.78 kcal/mol (step c).
Subsequently, the addition of the hydride palladium to the C@N
bond of imine would occur to give a transition states TS-1, with
free energy barrier +24.95 kcal/mol (step d). Then the transition
states TS-1 transform to transition states TS-2, with free energy
barrier of +26.75 kcal/mol (step e). Finally, the product was re-
leased and the ‘PdO2’ species was regenerated.

In conclusion, a simple iron oxide-supported palladium catalyst
was developed for the alkylation of amines with alcohols. The sim-
ple catalytic system exhibits high activity in the absence of base
and organic ligand. In general, good to excellent yields are achieved
using amines and alcohols containing various functional groups.
Importantly, catalyst characterization and DFT studies suggested
a novel mechanism with ‘PdO2/PdO’ as possible intermediate.
