A Brønsted acidic, ionic liquid containing, heteropolyacid functionalized polysiloxane network as a highly selective catalyst for the esterification of dicarboxylic acids

Abstract

<p>A novel acidic solid catalyst allows the monoesterification of a series of dicarboxylic acids with high selectivities.</p>

Single-Step Production of Bio-Based Methyl Methacrylate from Biomass-Derived Organic Acids Using Solid Catalyst Material for Cascade Decarboxylation–Esterification Reactions

“…This is because of the high acidity of the catalyst that promotes the esterification of IA and reduces MMA selectivity. 49 In contrast, the CHA catalyst showed a slightly better selectivity toward MMA (Table 2, entry 4). However, CHA-catalyzed cascade decarboxylation and esterification of IA produce numerous byproducts.…”

Ionic liquid‐assisted synthesis of 2‐amino‐3‐cyano‐4H‐chromenes: A sustainable overview

“…[11] Basically, ionic liquids (ILs) belong to a new type of salt-like material, called molten salt [12,13] that can remain liquid at normal or even at a lower temperature. With the concern of advanced research, these liquid materials have been widely used in various organic syntheses, [14][15][16][17][18][19] industrial processing, [20,21] catalysis, [22][23][24][25][26][27][28] biocatalytic reactions, [20,21,29,30] polymer science, [31,32] fuel cell, [33,34] nano-materials [35] and nanochemistry [36][37][38][39][40][41] and the influence of the ionic liquid as an efficient organocatalyst is acclaimed in large extent. [42][43][44][45][46] Moreover, the physical and chemical properties can be adjusted by changing the cation and anion fragment, and that's why the ILs have also been quoted as "designer solvents."…”

[ 42–46 ] Moreover, the physical and chemical properties can be adjusted by changing the cation and anion fragment, and that's why the ILs have also been quoted as “designer solvents.” On the other way, due to exhibiting acidic or basic properties, a specific functionalized ionic liquid substance can be prepared to afford the desired task‐specific ionic liquids (TSILs) which are quite a friendly reaction and are applied to a particular organic conversion.…”

Solvent‐free synthesis of compounds containing chromene core catalyzed by novel Brønsted acidic ionic liquids‐ClO4

“…[ 3–7 ] Therefore, non‐solvent applications of ILs emerging in the statue of “task‐specific ILs” are of particular importance. [ 8–11 ] Among them, Brønsted acidic ionic liquids (BAILs) due to numerous abundant advantages such as high thermal stability, high acidity, and simultaneously negligible release of hazardous gases, easy separation, and the ability to recycle and reuse for several times render the most important subset of task‐specific ILs.
