Abstract

The kinetics of the Mizoroki–Heck reaction was studied using a green catalyst consisting of Pd nanoparticles (Pd NPs) deposited on the bacterial cells of Paracoccus yeei (P. yeei) VKM B-3302. The study showed that the kinetics of the Mizoroki–Heck reaction catalyzed by Pd/P. yeei and the commercially available Pd/C, at first glance, did not differ significantly. However, more noticeable changes were found in the selectivity and specific productivity of the catalysts. Thus, the bacterial catalyst demonstrated an increase in selectivity for the target product with increasing process temperature. A probable reason for the concomitant increase in selectivity with temperature is the effect of Pd “release” from inside the bacterial cells as a result of their destruction under the action of the solvent and high temperature.
