Abstract
The influence of silica mesostructure upon the Pd-catalyzed selective oxidation of allylic alcohols has been investigated for amorphous and surfactant-templated SBA-15, SBA-16 and KIT-6 silicas. Significant rate enhancements can be achieved via mesopore introduction, most notably through the use of interconnected porous silica frameworks, reflecting both improved mass transport and increased palladium dispersion; catalytic activity decreases in the order Pd/KIT-6 Pd/SBA-16 > Pd/SBA-15 > Pd/SiO2. Evidence is presented that highly dispersed palladium oxide nanoparticles, not zero valent palladium, are the catalytically active species.
