Mechanoredox Chemistry as an Emerging Strategy in Synthesis

Chemistry - A European Journal, Journal Year: 2021, Volume and Issue: 27(38), P. 9721 - 9726

Published: April 1, 2021

Abstract Recent research endeavors have established that the mechanochemical activation of piezoelectric materials can open new avenues in redox chemistry. Impact forces, such as those imparted by a ball mill, been shown to transform barium titanate (BaTiO 3 ) into highly polarized state, which then donate an electron suitable oxidant and receive from reductant, mimicking photoredox catalytic cycles. Proof‐of‐concept studies elucidated mechanoredox chemistry holds great potential sustainable efficient radical‐based synthesis.

Enabling Sustainable Chemistry with Ionic Liquids and Deep Eutectic Solvents: A Fad or the Future?

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(37)

Published: July 5, 2022

Ionic liquids (ILs) and deep eutectic solvents (DESs) debuted with a promise of superior sustainability footprint due to their low vapor pressure. However, toxicity high cost compromise this footprint, impeding real-world applications. Fortunately, property tunability through rational selection precursors, including bioderived ones, provides strategy ameliorate toxicity, lower cost, endow new functions. This Review discusses whether ILs DESs are sustainable how they contribute chemical processes.
