A Green Approach for Producing Solvent-free Anisyl Acetate by Enzymecatalyzed Direct Esterification in Sponge-like Ionic Liquids Under Conventional and Microwave Heating
Bentham Science Publishers (2014)The biocatalytic synthesis of anisyl acetate fragrance was carried out by direct esterification of acetic acid with anisyl alcohol in sponge-like ionic liquids (SLILs), e.g. N,N,N,N-hexadecyltrimethylammonium bis(trifluo ... -
Design and synthesis of functionalized ionic liquids (ILs) using click chemistry tecniques
Universitat Jaume I (2016-07-28)Chemistry is a science devoted to the study of the properties and interactions between matter and energy. In other words, chemistry involves the study of the properties, characteristics, and physical and chemical changes ... -
Development of efficient processes under flow conditions based on catalysts immobilized onto monolithic supported ionic liquid-like phases
International Union of Pure and Applied Chemistry (2009)The introduction of imidazolium subunits into polystyrene-divinylbenzene (PS-DVB) polymers enables the preparation of a variety of catalytic systems. Those include the stabilization of catalytically active Pd nanoparticles ... -
New polymer-supported photocatalyst with improved compatibility with polar solvents. Synthetic application using solar light as energy source
Elsevier (2010)A new kind of supported photocatalysts derived from low-crosslinked polystrene, containing Rose Bengal and pyridinium groups, is described. Such polymers are capable to catalyze the quantitative synthesis of 5-hydroxy-5H ... -
Palladium N-Heterocyclic Carbene Catalysts for the Ultrasound-Promoted Suzuki-Miyaura Reaction in Glycerol
Wiley (2013-04-15)Novel palladium N-heterocyclic-carbene (NHC)-based complexes with 3,4,5-trimethoxybenzyl, alkyl and sulfonate N-substituents were obtained and fully characterized. The new complexes were used as pre-catalysts in the ... -
Tuning the Catalytic Efficiency of Palladium Supported Complexes (Pd-NHC-SILLPs): The Cooperative Effect of the Ionic Liquid-Like Groups
WILEY-VCH Verlag (2012)Gel-type Supported Ionic Liquid-like Phases (g-SILLPs) have been employed as medium for the preparation of Palladium carbene (Pd-NHC) complexes. These supported complexes onto ionic liquid-like phases were employed as ...
