Zeolite-catalyzed acetalization reaction of furfural with alcohol under solvent-free conditions

Acetalization reactions present a viable method for producing valuable chemicals and protecting carbonyl functionalities in organic compounds. Herein, several commercial zeolites were used as solid acid catalysts in the acetalization of biomass-derived furfural with alcohols under solvent-free conditions. The effects of major reaction parameters such as catalyst concentration, reaction temperature, and reaction time were investigated. Among the tested catalysts, SAPO-34 with appropriate acid sites and textural structure exhibited the highest catalytic activity under optimized reaction conditions. Additionally, the catalyst showed excellent recyclability and no obvious deactivation was observed even after using it six times.

Acetalization of carbonyl compounds catalyzed by acidic ionic liquid immobilized on silica gel

Imidazolium-silica heterogeneous catalyst (SG-[(CH2) 3SO3H-HIM]HSO4) was prepared by immobilization of acidic ionic liquid 1-(propyl-3-sulfonate) imidazolium hydrosulfate ([(CH2)3SO3H-HIM]HSO4) on silica-gel using tetraethoxysilane (TEOS) as silica source in this study. The properties of the samples were characterized by FT-IR, SEM and TG/DSC. The results suggested that [(CH2)3SO3H-HIM]HSO4 had been successfully immobilized on the surface of silica-gel and the immobilized ionic liquid catalyst SG-[(CH2)3SO 3H-HIM]HSO4 had good thermal stability. The original smooth surface of silica-gel was covered with [(CH2) 3SO3H-HIM]HSO4 and a rough surface of SG-[(CH2)3SO3H-HIM]HSO4 was formed, but the size of particles had no obvious change. Moreover, SG-[(CH 2)3SO3H-HIM]HSO4 exhibited high catalytic activity for a series of acetalization and could be recovered easily. After reused for 10 times in the synthesis of benzaldehyde ethanediol acetal, the catalyst could still give satisfactory catalytic activity.

1H NMR spectra, configuration, and conformations of 2-mono- and 2,4-disubstituted 1,3-dioxolanes

The stereochemistry of 2-furyl-substituted 1,3-dioxolanes was studied. The ethane fragment of 2-monosubstituted dioxolanes displays the spectrum that is typical for an AA'BB' spin system, while the spectra of the 2,4-disubstituted compounds are typical for an ABC system. The contribution of the various conformational forms to the pseudorotation cycle of the dioxolanes is discussed on the basis of an analysis of the spectra by means of an iteration program.
