Unveiling the Roles of Pt and CeO2 during Solvent-Free Amide Hydrogenation Utilizing Operando Photoelectron Photoionization Coincidence Spectroscopy

Paul Joseph Dyson, Xinbang Wu, Roland Christopher Turnell-Ritson

The hydrogenation of amides to amines is an important reaction in the synthesis of building blocks in organic chemistry. However, the solvent-free hydrogenation of amides (requiring heterogeneous catalysts and high reaction temperatures) is challenging, wi ...

Tandem catalysis enables chlorine-containing waste as chlorination reagents

Paul Joseph Dyson, Mingyang Liu, Xinbang Wu

Chlorinated compounds are ubiquitous. However, accumulation of chlorine-containing waste has a negative impact on human health and the environment due to the inapplicability of common disposal methods, such as landfill and incineration. Here we report a su ...

Thermally stable high-loading single Cu sites on ZSM-5 for selective catalytic oxidation of NH3

Paul Joseph Dyson, Xinbang Wu

Rigorous comparisons between single site- and nanoparticle (NP)-dispersed catalysts featuring the same composition, in terms of activity, selectivity, and reaction mechanism, are limited. This limitation is partly due to the tendency of single metal atoms ...

Versatile palladium-catalyzed double carbonylation of aryl bromides

Gabor Laurenczy, Paul Joseph Dyson, Cornel Fink, Xinbang Wu

A versatile palladium-catalyzed double carbonylation of aryl bromides has been developed. Using Pd(OAc)2/BuPAd2 as the catalyst system and DBU as the base, under relatively low CO pressure, various a-ketoamides were produced in good yields. In order to get ...
