Comparison of physicochemical properties of new ionic liquids based on imidazolium, quaternary ammonium, and guanidinium cations
Prashant S. Kulkarni,Luís C. Branco,João G. Crespo,M. Cristiana Nunes,Anabela Raymundo,Carlos A. M. Afonso +5 more
TL;DR: The features of the solid-liquid phase transition were analyzed, namely the glass transition temperature and the heat capacity jump associated with the transition from the non-equilibrium glass to the metastable supercooled liquid.
Journal ArticleDOI
Highly Selective Transport of Organic Compounds by Using Supported Liquid Membranes Based on Ionic Liquids
TL;DR: The potential for continuous separation of organic compounds based on the selective transport through supported liquid membranes that contain RTILs is shown, mainly because of the nonvolatile character ofRTILs and their solubility in the surrounding phases.
Journal ArticleDOI
Pyridinium salts: from synthesis to reactivity and applications
Subbiah Sowmiah,Subbiah Sowmiah,José M. S. S. Esperança,Luís Paulo N. Rebelo,Carlos A. M. Afonso +4 more
TL;DR: This review aims at highlighting the pyridinium salts in terms of their synthetic routes, reactivity and their importance as pyrIDinium ionic liquids, as p Pyrid inium ylides, as anti-microbial, anti-cancer,Anti-malarial and anti-cholinesterase inhibitors, as well as their applications in materials science and biological issues related to gene delivery.
Journal ArticleDOI
Studies on the density, heat capacity, surface tension and infinite dilution diffusion with the ionic liquids (C4mim)(NTf2), (C4mim)(dca), (C2mim)(EtOSO3) and (Aliquat)(dca)
Carlos A. Nieto de Castro,Elisa Langa,Ana L. Morais,M.L.M. Lopes,Maria José Lourenço,Fernando J. V. Santos,M. Soledade C.S. Santos,José N. Canongia Lopes,Helena Veiga,Mafalda Macatrão,José M. S. S. Esperança,Carolina S. Marques,Luís Paulo N. Rebelo,Carlos A. M. Afonso +13 more
TL;DR: In this article, a new project on synthesis and characterization of new and not-so-new ionic liquids was started, where binary diffusion, electrical conductivity, heat capacity, surface tension, viscosity and thermal conductivity were studied.
Journal ArticleDOI
Synthesis of Chiral Cyclopentenones.
TL;DR: This Review provides an overview of reported methods for enantioselective and asymmetric syntheses of cyclopentenones, including chemical and enzymatic resolution, asymmetric synthesis via Pauson-Khand reaction, Nazarov cyclization and organocatalyzed reactions, asymmetrical functionalization of the existing cyclopENTenone unit, andfunctionalization of chiral building blocks.
