Hardly any industrial process can utilize CO2<\/sub> directly as a raw material, but why is it so difficult to turn CO2<\/sub> into something useful? Due to the highest oxidized state of carbon, CO2<\/sub> is so stable that it can be even used as fire extinguisher, and potent catalysts are required to overcome its thermodynamic and kinetic barrier.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Org.

Using 4-acyl-Hantzsch ester radical reservoirs, various Michael acceptors, enones and para-quinone methide substrates could be used. The protocol enabled further derivatizations and it could also be extended to a few unactivated alkenes. Moreover, the nature of the radical process was also investigated.<\/p> <\/p> \u00a0<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t J.

With a growing focus on sustainable technologies, ionic liquids have emerged as tunable solvents for multiple applications but are often too viscous or expensive for use as bulk solvent. As a result, there has been a tremendous increase in interest in the behavior of ionic liquids in the presence of water. It has already been shown that certain ionic liquids act as surfactants in aqueous solutions, enabling the combination of both solvents to afford solvent systems with unique properties. Ultimately, surface-active ionic liquids in water give rise to distinct chemistry of their own compared to traditional molecular solvents, and thus their use is rapidly growing. In this review, the general structure of surface-active ionic liquids and the key features that allow aggregation in water to give micellar structures is discussed. Furthermore, characterization techniques of the formed micelles are presented, discussing aggregation and possible methods of studying micellization behavior. Finally, current applications of surface-active ionic liquids across all fields of chemistry, from traditional organic chemistry to nanoparticle synthesis are presented.<\/p> <\/p> \u00a0<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t ChemSusChem (2022<\/strong>) 15, e202102262<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t The wide application range and ascending demand for platinum group metals combined with the progressive depletion of their natural resources renders their efficient recycling a very important and pressing matter. Primarily environmental considerations associated with state-of-the-art recovery processes have shifted the focus of the scientific community toward the investigation of alternative recycling approaches. Within this context, ionic liquids have gained considerable attention in the last two decades chiefly sparked by properties such as tunabilty, low-volatility, and relatively easy recyclability. In this review an understanding of the state-of-the-art processes, including their drawbacks and limitations, is provided. The core of the discussion is focused on platinum group metal recovery with ionic liquid-based systems. A brief insight in some environmental considerations related to ionic liquids is also provided while some discussion on research gaps, common misconceptions related to ionic liquids and outlook on unresolved issues could not be absent from this review.<\/p> <\/p> \u00a0<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t Green Chem.
