| Abstract: | One-pot synthesis of (2-furanylmethylene)malononitrile, a Knoevenagel product of furfural with malononitrile, from xylose efficiently proceeded by combined use of acid Amberlyst-15 and acid-base Cr/hydrotalcites with 44% yield. Structural characterizations were carried out using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), X-ray absorption spectra, and nitrogen adsorption measurements. The Lewis acidic properties of a highly active Cr/HT were investigated using Meerwein-Ponndorf-Verley (MPV) reaction. It was confirmed that the prepared Cr/HT possessed the Lewis acid Cr2O3 on HT surface. Thus, the combined use of dispersed Lewis acid Cr2O3 and Brønsted base HT facilitated the isomerization step of aldose into ketose, and strongly promoted activity for the synthesis of furfural derivatives from aldoses through isomerization, dehydration and Knoevenagel condensation reactions in one-pot manner. |
