Chitin represents an abundant source of nitrogenous polysaccharides, making it a suitable feedstock for organonitrogen platform chemicals. In particular, furanic compounds, such as 3-acetamido-5-acetylfuran (3A5AF), can be readily obtained. Furans can be further functionalized using a Diels–Alder (DA) …

The synthesis of aromatic compounds from biomass-derived furans is a key strategy in the pursuit of a sustainable economy. Within this field, a Diels–Alder/aromatization cascade reaction with chitin-based furans is emerging as a powerful tool for the synthesis of nitrogen-containing aromatics. In this …

Het onderzoek beschreven in deze scriptie richt zich op de asymmetrische hydrogenering van cyclohexadienen tot chirale cyclohexanen. Via een regioselectieve kobalt gekatalyseerde Diels-Alder reactie zijn 1,3-gesubstitueerde cyclohexenen gesynthetiseerd. Deze cyclohexenen dienen als substraten voor de …

A series of new, easily synthesized C60-fullerene derivatives is introduced that allow for optimization of the interactions between rr-P3HT and the fullerene by systematic variation of the size of the ester group. Two compounds gave overall cell efficiencies of 4.8%, clearly outperforming [60]PCBM which …

For the recycling of carpet and artificial turf the latex backing is often a real stumble block. Many strategies have been developed like freezing the carpet, followed by grinding and subsequent separation of the milled particles. Once it has been separated from its backing materials, PA 6 is relatively …

In this article, we review the recent progress that has been made in the field of Lewis-acid catalysis of carbon carbon-bond-forming reactions in aqueous solution. Since water hampers the hard hard interactions between the catalyst and the reactant, it often complicates catalysis. However, once coordination …
