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

Comparative study of homogeneous hydrogenation of d-glucose and d-mannose catalyzed by water soluble [Ru(tri(m-sulfophenyl) phosphine)] complex
Snježana Kolarić,Vitomir Šunjić +1 more
TL;DR: In this paper, homogeneous hydrogenation of two epimeric aldoses, d -glucose (d -Glc) and d -mannose ( d -Man) was performed in water, with molecular hydrogen and by transfer hydrogenation catalyzed by [Ru-TPPTS] complex (TPPTS = trisodium salt of tri(m -sulfophenyl)phosphine).

Diastereoselective control in ketose hydrogenations with supported copper and nickel catalysts
TL;DR: In this article, a series of Cu and Ni catalysts has been studied in ketose hydrogenations, showing that the preferred products of Cu catalysis fit a particular stereochemical trend and those from modified Ni systems the opposite trend, demonstrating control by the catalysts through 1,2-asymmetric induction.
