Article Synopsis
- The study explores ionothermal carbonization (ITC) as a method to create nanostructured carbon materials, known as ionochars, using lignocellulosic biomass in specific ionic liquids (ILs).
- Previous research focused on how the imidazolium cation affects the properties of these ionochars, but the role of the chloroferrate anion needed further investigation.
- This research revealed that different anionic components significantly influence the ionochars' texture and morphology, utilizing various analytical techniques to characterize their properties.
Thia-Michael additions (1,4-additions of a thiol to a Michael acceptor) are generally catalyzed by an external Brønsted or Lewis base. A spontaneous (uncatalyzed) Michael addition of thiols to α-trifluoromethyl acrylates is described, as well as its application to the very efficient preparation of a thermoset. A thorough mechanistic investigation, based on an experimental kinetic study and on DFT calculations, is presented for the addition of arene- and alkanethiols to tert-butyl trifluoromethyl acrylate in polar aprotic solvents, unveiling a probable solvent-assisted proton transfer in the rate-determining step and a considerable lowering of the energy barrier induced by the CF group.
