Two synthetic routes, starting from glycidyl ethers or epichlorohydrin are proposed in order to obtain a series of [N20R]X ILs with varying alkyl chains (R) and anions (X−), including chloride, triflate, bistriflimide, formate, and lactate. Comprehensive characterization of the ILs has been carried out, revealing tunable physicochemical properties, such as density (1.03–1.40 g cm−3), viscosity (0.3–189 Pa s), and thermal stability (up to 672 K), influenced by structural modifications. The ILs demonstrated their applicability in two key applications: solubilizing hydroxycinnamic acids outperforming traditional solvents, and serving as recyclable media for Pd nanoparticle-catalyzed Heck–Mizoroki coupling, achieving quantitative yields and selectivity. These glycerol-derived ILs combine sustainability with functionality, offering a versatile platform for green chemistry applications. info:eu-repo/grantAgreement/ES/DGA/E37-23R info:eu-repo/grantAgreement/ES/MICINN/PID2023-147656OB-I00 info:eu-repo/grantAgreement/ES/MINECO/PID2021-125762NB-I00 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Barrio, Jesús del Universidad de Zaragoza (orcid)0000-0002-5380-6863 Leal-Duaso, Alejandro (orcid)0000-0002-3256-2089 Mayoral, José A.
