Hydrogenolysis Goes Bio: From Carbohydrates and Sugar Alcohols to Platform Chemicals
TLDR
Past and present developments in hydrogenolysis reactions are highlighted, with special emphasis on the direct utilization of cellulosic feedstocks, to bridge currently available technologies and future biomass-based refinery concepts.Abstract:
In view of the diminishing oil resources and the ongoing climate change, the use of efficient and environmentally benign technologies for the utilization of renewable resources has become indispensible. Therein, hydrogenolysis reactions offer a promising possibility for future biorefinery concepts. These reactions result in the cleavage of C-C and C-O bonds by hydrogen and allow direct access to valuable platform chemicals already integrated in today's value chains. Thus, hydrogenolysis bears the potential to bridge currently available technologies and future biomass-based refinery concepts. This Review highlights past and present developments in this field, with special emphasis on the direct utilization of cellulosic feedstocks.read more

Selective production of glycols from xylitol over Ru on covalent triazine frameworks – suppressing decarbonylation reactions
Anna Katharina Beine,Andreas J. D. Krüger,Jens Artz,Claudia Weidenthaler,Christoph Glotzbach,Peter J. C. Hausoul,Regina Palkovits +6 more
TL;DR: Ru on covaltent triazine frameworks (CTF) are highly active and selective catalysts for the conversion of xylitol to glycols (80% C-yield) in basic media with increasing N-content decarbonylation reactions are suppressed leading to high glycol selectivity.

Investigation of the mechanism of the selective hydrogenolysis of CO bonds over a Pt/WO3/Al2O3 catalyst
TL;DR: In this article, the authors investigated the hydrogenolysis of various polyols and ethers over a Pt/WO3/Al2O3 catalyst and found that the dissociation position of the C O bond strongly depended on the stability of the carbocation intermediate, and that hydrogenization via a secondary carbocation as an intermediate proceeded preferentially to that via a primary carbocation.

A nanospherical ordered mesoporous Lewis acid polymer for the direct glycosylation of unprotected and unactivated sugars in water.
TL;DR: In the C-glycosylation reaction between D-glucose and dimedone with the Sc(OTf)2-NSMP catalyst, the conversion was 99% and the yield of xanthone-C- glucoside reached 92% after 2 days, which exceeded the previous best results.
