Three different Pd0 -based heterogeneous catalysts were developed and tested in the Cassar-Heck reaction (i. e., copper-free Sonogashira reaction) aiming at the definition of a waste minimized protocol. The cross-linked polymeric supports used in this investigation were designed to be adequate for different reaction media and were decorated with di...

In this work, high-density jet fuel range cycloalkanes were synthesized in high yields (similar to 80%) by solvent-free aldol condensation of cyclopentanone and furfural followed by hydrodeoxygenation (HDO). Sodium-promoted magnesium-aluminum mixed oxides (Na-MgAlO) exhibited a high catalytic activity in the aldol condensation of cyclopentanone and...

In recent years, the work of various research groups has allowed the substitution of the hazardous solvents most widely used in solid-phase peptide synthesis, namely DMF, NMP, DCM, DEE, among others, by several much less hazardous solvents. Indeed, greener alternatives have been found for almost all steps of the process, with the exception of the c...
A series of magnetic zirconium nanoparticles with varied Zr/Fe molar ratios were synthesized and developed as acid - base bifunctional catalysts in the catalytic transfer hydrogenation (CTH) of biomass-derived furfural (FFR) and levulinic acid (LA) using 2-propanol as both hydrogen donor and solvent. Zirconium constituents coated on nano-sized Fe3O...

Hydrodeoxygenation (HDO) of lignocellulose-derived oxygenates to diesel or jet fuel range C8-C18 alkanes usually requires harsh reaction conditions. A fairly mild (160 degrees C, 4 MPa H-2) one-pot catalytic HDO system based on Ru/HAP combined with the HZSM-5 catalyst was developed, and a series of diesel or jet fuel range alkanes (C8-C18), includi...

Lignocellulosic hydrolysate contains complex nonsugar compounds and undegraded sugars in the process of preparing platform compound levulinic acid (LA) and furfural by one-step dilute-acid hydrolysis. For efficiently and comprehensively utilizing the hydrolysate, a series of polar modified resins were synthesized for adsorption and separation of th...
