Abstract:

The transformation of biofeedstock into higher value bulk and fine chemicals is of paramount importance to become fully independent of fossil fuels. Using homogeneous catalysis for such valorization processes allows for highly selective transformation to be carried out under mild conditions. Here, we demonstrate the use of homogeneous PNP transition metal complexes for catalyzing a range of biofeedstock valorization processes. In addition, we show how this catalyst type may be used for hydrogen storage in organic compounds. For example (bio)ethanol may be transformed to to sodium acetate, ethyl acetate, or butanol. Likewise, potassium lactate is produced from glycerol and gamma-valerolactone is made from levulinates. Furthermore, we show how methanol, (bio)ethanol, isopropanol, glycerol, sugar alcohols, and carbohydrates all are well tolerated substrates for extruding hydrogen molecules.
