reaction. The leaching of rhodium was detected by ICP-AES and the
results were presented in Table 2. It can be seen that the leaching
of rhodium decreases with the increase of recycle number. The
reason for this needs further investigation. Nevertheless, compared
with our previous complex catalyst in TRPTC system, the average
leaching of rhodium (0.2 wt.%) is lower.

Extension of the hydrogenation reaction to other substrates
including styrene, 1-octene, 1-dodecene and 1,5-cyclooctadiene
afforded the high conversion as shown in Table 3. Both styrene
and 1,5-cyclooctadiene could completely convert into ethyl ben-
zene and cyclooctane, respectively, at 60 °C and initial H2 pressure
of 1 MPa (entries 1 and 4).

To summarize, we have demonstrated for the first time that the
thermoregulated ligand Ph2P(CH2CH2O)nCH3 (n = 16)-stabilized
rhodium nanoparticles are not only with the property of TRPTC
but also active, stable and recyclable catalyst for hydrogenation
of olefins in the aqueous/1-butanol biphasic system. Perhaps most
importantly, however, the methodology of TRPTC of nanoparticles
is simple to realize and the catalyst is easy to separate from the
product and recycle. Therefore, it opens up a new avenue for recov-
ery and recycling of soluble transition-metal nanoparticle catalyst,
especially for noble transition-metal nanoparticle catalyst.
