Resumen: | Se realizó la síntesis de nueve complejos lantánidos de cerio, neodimio y samario con ligandos trans-cinamato (L1), trans-p-clorocinamato (L2) y trans-p-metoxicinamato (L3). La caracterización se realizó mediante espectroscopia FT-IR, análisis térmicos (TGA y DSC) y análisis elemental. Los compuestos obtenidos se utilizaron como catalizadores para la oxidación de canfeno y β-pineno, usando peróxido de hidrógeno (30 %) y ácido peracético (12 %) como agentes oxidantes. En la oxidación de canfeno, el complejo [Nd(L2)3] presentó la conversión más alta (97.99 %) con una selectividad del 84.05 % hacia el ácido 3-canfenilocarboxílico, mientras que en la oxidación de β-pineno, el complejo [Ce(L3)3 . 2H2O] presentó la conversión más alta (82.62 %) con una selectividad hacia la nopinona del 70.52 %. |
Abstract: | The synthesis of nine lanthanide complexes of cerium, neodymium and samarium with ligands trans-cinnamate (L1), trans-p-chlorocinnamate (L2) and trans-p-methoxycinnamate (L3) was carried out. The characterization performed by FT-IR spectroscopy, thermal analysis (TGA and DSC) and elemental analysis. The compounds obtained were used as catalysts for the oxidation of camphene and β-pinene, using hydrogen peroxide (30%) and peracetic acid (12%) as oxidizing agents. In the oxidation of camphene, the [Nd(L2)3] complex, showed the highest conversion (97.99%) with a selectivity of 84.05% towards 3-can phenyl carboxylic acid, while in β-pinene oxidation, the [Ce(L3)3.2H2O] complex, showed the highest conversion (82.62%) with a selectivity towards the nopinone of 70.52%. |
