MDPI – Catalysts

Despite their high atomic dispersion, single site catalysts with Pt supported on CeO2 were found to have a low activity during oxidation reactions. In this study, we report the behavior of Pt/CeO2 single site catalyst under more complex gas mixtures, including CO, C3H6 and CO/C3H6 oxidation in the absence or presence of water.

The Chemical Record

Asymmetric Pd-catalyzed Tsuji-Trost-type allylation is an important catalytic reaction toward chiral natural and unnatural product syntheses. We successfully modified a desalt-type reaction using allyl ester or halide to a dehydrative one using allylic alcohol via the establishment of two redox-mediated donor acceptor bifunctional catalyst systems.

Since the 1990s, concerted attempts have been made to improve the efficiency of medicinal chemistry synthesis tasks using automation. Although impacts have been seen in some tasks, such as small array synthesis and reaction optimization, many synthesis tasks in medicinal chemistry are still manual.
