@article{Crespo_Domínguez_Baricelli_Borusiak_Omaña_Castro_Rosales_2020, title={BIPHASIC HYDROGENATION OF EUGENOL WITH RUTHENIUM AND RHODIUM NANOPARTICLES STABILIZED IN IONIC LIQUIDS}, volume={65}, url={https://jcchems.com/index.php/JCCHEMS/article/view/831}, abstractNote={<p>The purpose of this study was to evaluate on the catalytic activity nanostructured systems of ruthenium and rhodium stabilized in ionic liquids derived from imidazole: IL<sub>1</sub>= butylmethyllimidazole tetrafluoroborate [BMIM][BF<sub>4</sub>] and IL<sub>2</sub>= butylmethylimidazole hexafluorophosphate [BMIM][PF<sub>6</sub>] in the biphasic hydrogenation of eugenol under mild reaction conditions T= 80ºC, P= 100psi during 4 hours. The metallic nanoparticles (NPs-M) were synthesized using the ligand hydrogenation displacement reaction for the ruthenium III tris(acetylacetonate), [Ru(acac)<sub>3</sub>], and bis-μ-cloro-di(1,5-ciclooctadieno) dirhodium(I), [Rh(COD)Cl]<sub>2</sub>, showing a mean particle size between (2.00±0.04) nm and (4.0±0.2) nm. The nanostructured systems Rh/IL<sub>2</sub>, Ru/IL<sub>2</sub> and Ru/IL<sub>1 </sub>show similar activities and different from the Rh/IL<sub>1</sub> system. On the other hand, the systems stabilized in the IL<sub>1</sub> were more selective towards the formation of the 2-methoxy-4-propylphenol than the systems stabilized in the IL<sub>2</sub>. Nevertheless, in general, the catalysts were good for hydrogenating eugenol, resulting in Rh/IL<sub>1</sub> nanoparticles less reactive than Rh/IL<sub>2</sub>, Ru/IL<sub>1</sub> and Ru/IL<sub>2</sub>.</p> <p><img src="/public/site/images/icrespo/Imagen1.jpg" alt=""></p&gt;}, number={4}, journal={Journal of the Chilean Chemical Society}, author={Crespo, Isis and Domínguez, Olgioly and Baricelli, Pablo and Borusiak, Margarita and Omaña, Ofelia and Castro, William and Rosales, Merlin}, year={2020}, month={Nov.}, pages={4982-4987} }
