| Abstract: | Pd-containing Al-SBA-15 materials were prepared and characterized in view of their utilization in the two-step valorization of trans-ferulic acid into stilbenes via tandem decarboxylation/Mizoroki-Heck coupling. Materials were found to be highly active and selective in the proposed chemistries, with quantitative conversion to target products under mild reaction conditions (typically 100 °C, 3–6 h reaction). Relevant insights on catalyst deactivation via sintering (Pd nanoparticles agglomeration) were also observed for the synthesized materials. |
