Introduction of versatile and recyclable network poly (ionic liquid)s as an efficient solvent with desired properties for application in C C cross-coupling reactions

Sustainable preparation of 2-acylbenzothiazoles under the cooperation of ionic liquids and microwave irradiation

“…18 ILs possess the advantages of both homogeneous materials, facilitating a wide range of organic reactions, including Knoevenagel condensations, 19 aldol reactions, 20 esterification, 21 and cross-coupling reactions. 22 Meanwhile, the utilization of microwave irradiation has received considerable attention due to its unique feature of instantaneous “in-core” heating selectively and homogeneously, resulting in accelerated syntheses. 23 Considering the successful development of an acid-functionalized IL under microwave irradiation for the synthesis of functionalized molecules, 24 there is a great desire to establish a straightforward and sustainable catalytic system to address the remaining challenges and achieve 2-acylbenzothiazole synthesis under metal-free conditions.…”
