at around 60% in the following runs (runs 3 and 5–7). The
decrease in the selectivity could be ascribed to the change of
catalytic active species during the reaction as suggested from
the color changes of the reaction mixture from orange (fresh)
to deep red (after reaction), similar to the result reported in the
literature.[26,27] In addition, the results of the UV–vis absorption
spectra of the catalyst in H2O–PEG (Fig. 2) also revealed that
the active species changed during the reaction. No absorbance
peak was observed for the fresh catalyst mixture; however, a
broad peak appeared between wavenumbers of 300 and 400 nm
when the reaction was conducted for 20 min and it shifted to
distinguish two peaks at the wavenumbers of 380 and 489 nm
after the reaction for 1 h. Such a change in the Ru catalytic
species during the reaction was also reported previously in the
literature.[28–32] In the present reaction system, the Ru leached
into the organic phase was less than 1% of original Ru in each
recycling from ICP analysis, suggesting that the Ru complexes
could be immobilized in the mixed solvent of H2O and PEG
successfully.

Conclusions
We have developed a practical and green method for the transfer
hydrogenation of citral to citronellol using [RuCl2(benzene)]2
catalyst immobilized in a mixture of H2O and PEG. The high
selectivity to citronellol of 92.4% was achieved with HCOONa as
hydrogen source. The Ru complexes could be immobilized in
the H2O–PEG phase and separated from the organic products
successfully, and the catalysts could keep the same catalytic
activityafterthefirstrun,althoughtransformationofactivespecies
occurred.
