The glycosidation of 2,3,4-triacetyl-1-bromo-α-d-xylopyranose with various terpenols occurs at 50°C in DMF without the requirement of any additive. The decisive role of DMF as solvent on the coupling efficiency is highlighted.
Microwave-induced esterification of cellulose in homogeneous phase has been investigated. Cellulose was first solubilized in the solvent system LiCl/N,N-dimethylacetamide and then esterified by lauroyl chloride in the presence of N,N-dimethyl-4-aminopyridine. Microwave activation resulted in a drastic reduction of reaction time (1 min) compared to conventional heating. The mechanical and thermal properties...
