Controlling lignin solubility and hydrogenolysis selectivity by acetal-mediated functionalization

Jeremy Luterbacher, Anastasiia Komarova, Graham Reid Dick

Existing lignocellulosic biomass fractionation processes produce lignin with random, interunit C-C bonds that inhibit its depolymerization and constrain its use. Here, we exploit the aldehyde stabilization of lignin to tailor its structure, functionality, ...

Lignin First: Confirming the Role of the Metal Catalyst in Reductive Fractionation

Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Antoine Philippe Van Muyden, Lu Chen, Ning Yan, Xinjiang Cui

Rhodium nanoparticles embedded on the interior of hollow porous carbon nanospheres, able to sieve monomers from polymers, were used to confirm the precise role of metal catalysts in the reductive catalytic fractionation of lignin. The study provides clear ...

Photochemical Functionalization of Heterocycles with EBX Reagents: C-H Alkynylation versus Deconstructive Ring Cleavage

Jérôme Waser, Marion Marie-Agnès Garreau

The development of novel methodologies for the functionalization of saturated heterocycles is highly desirable. Herein, we report a cheap and efficient photochemical method for the C-H functionalization of saturated O-heterocycles, as well as the deconstru ...

A novel reactor concept for thermal integration of naphtha reforming with propane ammoxidation

Alimohammad Bahmanpour, Samira Ebrahimian

In this study, propane ammoxidation as an exothermic process is thermally coupled with the endothermic naphtha reforming process which resulted in the elimination of the naphtha reforming furnaces. Both processes are available in petrochemical plants. Naph ...

Nickel-Catalyzed Regioselective Hydroalkylation and Hydroarylation of Alkenyl Boronic Esters

Xile Hu, Srikrishna Bera

Metal hydride catalyzed hydrocarbonation reactions of alkenes are an efficient approach to construct new carbon-carbon bonds from readily available alkenes. However, the regioselectivity of hydrocarbonation remains challenging to be controlled. In nickel h ...

Metal-Sulfide Catalysts Derived from Lignosulfonate and their Efficient Use in Hydrogenolysis

Paul Joseph Dyson, Xile Hu, Zhaofu Fei, Antoine Philippe Van Muyden, Xiang Li, Lichen Bai, Xinjiang Cui, Sijie Liu

Catalytic lignosulfonate valorization is hampered by the in situ liberation of sulfur that ultimately poisons the catalyst. To overcome this limitation, metal sulfide catalysts were developed that are able to cleave the C-O bonds of lignosulfonate and are ...

New insights into the effect of nitrogen incorporation in Mo: catalytic hydrogenation vs. hydrogenolysis

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

The catalytic effect of nitrogen incorporation into Mo on hydrogenation (of -NO2 to -NH2 in nitrobenzene to aniline) and hydrogenolysis (of -C?O in benzaldehyde to toluene) processes has been assessed. Bulk Mo was prepared by temperature programmed reducti ...

Discovery of a Highly Active Catalyst for Hydrogenolysis of C-O Bonds via Systematic, Multi-metallic Catalyst Screening

Paul Joseph Dyson, Antoine Philippe Van Muyden, Ning Yan, Sviatlana Siankevich

Hydrogenolysis of C-O bonds is a highly challenging reaction with the most efficient catalysts based on bimetallic assemblies. Systematic studies to identify the optimum metal combination have not been performed and, therefore, we designed a method to scre ...
