Towards a methanol economy based on homogeneous catalysis: methanol to H2 and CO2 to methanol

2015, Alberico, E., Nielsen, M.

The possibility to implement both the exhaustive dehydrogenation of aqueous methanol to hydrogen and CO2 and the reverse reaction, the hydrogenation of CO2 to methanol and water, may pave the way to a methanol based economy as part of a promising renewable energy system. Recently, homogeneous catalytic systems have been reported which are able to promote either one or the other of the two reactions under mild conditions. Here, we review and discuss these developments.

Enantio- and diastereoselective synthesis of γ-amino alcohols

2015, Verkade, Jorge M. M., Quaedflieg, Peter J. L. M., Verzijl, Gerard K. M., Lefort, Laurent, van Delft, Floris L., de Vries, Johannes G., Rutjes, Floris P. J. T.

The γ-amino alcohol structural motif is often encountered in drugs and natural products. We developed two complementary catalytic diastereoselective methods for the synthesis of N-PMP-protected γ-amino alcohols from the corresponding ketones. The anti-products were obtained through Ir-catalyzed asymmetric transfer hydrogenation, the syn-products via Rh-catalyzed asymmetric hydrogenation.

Single molecule level plasmonic catalysis – a dilution study of p-nitrothiophenol on gold dimers

2015, Zhang, Zhenglong, Deckert-Gaudig, Tanja, Singh, Pushkar, Deckert, Volker

Surface plasmons on isolated gold dimers can initiate intermolecular reactions of adsorbed p-nitrothiophenol. At the single molecule level when dimerization is not possible an intramolecular reaction can be observed. Experimental evidence indicates that plasmon-induced hot electrons provide the required activation energy.
