The latest issue of Green Chemistry – issue 5 – is now published online.
The front cover of this issue features work by James Dumesic and co-workers from the University of Wisconsin-Madison, USA. In this paper, the authors report the selective hydrogenation of biomass-derived 5-hydroxymethylfurfural using heterogeneous catalysts. A variety of supported catalysts in monophasic and biphasic reactions systems were studied to determine the effects of the metal, support, solution phase acidity and solvent on the selectivity of the reaction. The authors found that Ru supported on materials with high isoelectric points (e.g. ceria and γ-alumina) gave the highest yields.

The inside front cover of this issue highlights work by Klavs Jensen and Xiaoying Liu from Massachusetts Institute of Technology, USA, who report the direct oxidative amidation of aromatic aldehydes in a continuous flow microreactor system using aqueous hydrogen peroxide. This method allows amides to be synthesized from secondary amines and aromatic aldehydes in a single operation under mild conditions within 15-40 mins. The procedure does not require catalysts or promoting reagents.
