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

Synthesis of high viscosity, ecofriendly, and low melting point poly(ionic liquid)s (LMP-PIL) with network structure has been introduced by the reaction 1,1′,1′′‑(1,3,5‑triazine‑2,4,6‑triyl) tris(3‑methyl‑1H‑imidazol‑3‑ium) iodide ionic liquid (TAIm[I] IL) monomer disodium salts various open-chain carboxylic acids as well sulfonic via a polycondensation on counter ions (PC-CI). Change in alkyl group length carboxylate, sulfonate, provide broad spectrum properties terms density, solubility for resulting PILs. The physical PILs including, point, boiling density,M¯n, polydispersity (Ð), were determined this study. Also, thermal behavior studied comparison corresponding monomers. ecofriendly served an efficient solvent ligand Cu-catalyzed Heck Sonogashira CC coupling reactions. High to excellent yields obtained products under mild conditions at points could be direct scalability. prepared recycled several times from homogenous mixture preservation intrinsic properties. detailed study was conducted mechanism
