Formation of 5-methylfurfural and 2-acetylfuran from lignocellulosic biomass and by Cr3+-catalyzed dehydration of 6-deoxyhexoses
(Peer reviewed; Journal article, 2022)During autocatalyzed steam explosion of lignocellulose, polysaccharides in the cell wall are hydrolyzed and dehydrated to form various furaldehydes. In addition to furfural, 5-methylfurfural and 2-acetylfuran were identified ... -
Nitropyridines in Organic Synthesis. 2.5-Disubstituted Pyridine Compounds
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:34, Doctoral thesis, 2004)The goal of this project was to explore how 5-nitropyridine-2-sulfonic acid (18) and its potassium salt (18a) could be utilised as starting materials for 2,5- substituted pyridines. Compounds 18/18a were prepared by oxidation ...
