En la presente tesis se postulan diferentes rutas para la obtención de productos químicos valiosos a partir de derivados oleoquímicos. La metátesis cruzada de ésteres de ácidos grasos (FAME's) con alquenos es una manera elegante de sintetizar homólogos de estos ésteres, y extender ampliamente la versatilidad de la reacción de metátesis en el campo de la oleoquímica. En este trabajo se estudió la reacción de metátesis cruzada de oleato de metilo con 3-pentenonitrilo, cinamaldehído y etileno, en fase líquida, empleando el complejo de Hoveyda-Grubbs de segunda generación como catalizador. Además, se estudió la posibilidad de utilizar un catalizador sólido en las reacciones estudiadas, el cual se sintetizó inmovilizando el complejo de Hoveyda Grubbs en sílice.
In the present thesis, different routes for the production of valuable chemicals from oleochemical derivatives are postulated. Cross-metathesis of fatty acid esters (FAME) with alkenes is an elegant way to synthesize homologs of these esters and extend extensively the versatility of the metathesis reaction in the field of oleochemistry. In this work, the cross-metathesis of methyl oleate with 3-pentenenitrile, cinnamaldehyde, and ethylene in the liquid phase was studied using the second-generation Hoveyda-Grubbs complex as a catalyst. In addition, the possibility of using a solid catalyst was studied, which was synthesized immobilizing the Hoveyda Grubbs complex in silica.
