“…Important sectors include paints and pharmaceuticals ( Figure 2 ) [ 26 ]. The solvent is often the major component of a formulation, a reaction, or an extraction [ 27 ]. As such a significant alleviation of non-renewable chemical dependence can be achieved with the implementation of bio-based solvents.…”

The global bio-based chemical market is growing in size and importance. Bio-based solvents such as glycerol and 2-methyltetrahydrofuran are often discussed as important introductions to the conventional repertoire of solvents. However adoption of new innovations by industry is typically slow. Therefore it might be anticipated that neoteric solvent systems (e.g., ionic liquids) will remain niche, while renewable routes to historically established solvents will continue to grow in importance. This review discusses bio-based solvents from the perspective of their production, identifying suitable feedstocks, platform molecules, and relevant product streams for the sustainable manufacturing of conventional solvents.

SummaryPd-catalysed C–C bond formation is an essential tool within the pharmaceutical and agrochemical industries. Many of these reactions rely heavily on polar aprotic solvents; however, despite their utility, these solvents are incompatible with the drive towards more sustainable chemical synthesis. Herein, we describe the scope and limitations of an alternative to DMF derived from renewable sources (CyreneTM) in Sonogashira cross-coupling and Cacchi-type annulations.

“…In the past few years, a great effort has been devoted to the study of ionic liquids (ILs) due to their peculiar chemical–physical properties such as negligible vapor pressure, high ion conductivity, and high thermal stability. − The most important driving force of the booming research on ILs, typically including those based on imidazolium, pyrrolidinium, ammonium, phosphonium, guanidinium, and pyridinium, is their potential in substituting for volatile organic solvents in chemical synthesis. , …”

A series of ammonium-based ionic liquids (ILs), which share a homologous series of cations (CH3CH2)3N+(C n H2n+1) with n = 2, 4, 6, 8 and the anions with either BF4 –, PF6 –, or SbF6 –, was synthesized. Their structures were confirmed by 1H and 13C NMR, ESI-MS, and elemental analysis. Meanwhile, the content of impurity (e.g., water and bromide ions) was also determined using Karl Fischer titrator and ion chromatography. The thermal properties of the ILs were determined by TGA and DSC. Five of the investigated ILs have been shown to have a low melting point (< 100 °C): N,N,N,N-tetraethylammonium tetrafluoroborate, [N2222]BF4, N,N,N,N-tetraethylammonium hexafluorophosphate, [N2222]PF6, N,N,N-triethylhexylammonium tetrafluoroborate, [N2226]BF4, N,N,N-triethyloctylammonium hexafluorophosphate, [N2228]PF6 and N,N,N-triethyloctylammonium hexafluoroantimonate, [N2228]SbF6. Densities, refractive indices, and miscibility of these 12 ILs were well studied systematically. Moreover, from the analysis of the structure–property relationship, the role of the alkyl chain length of the cation on these physical properties of the ILs has been assessed, and the influence of the nature of the anions on these experimental data of the ILs has been discussed. The studies may provide valuable contributions for the design and study of ILs.
