Abstract Chemical recycling of plastic wastes is great significance for sustainable development, which also represents a largely untapped opportunity the synthesis value-added chemicals. Herein, we report novel and general strategy to degrade polyesters via directly breaking C alkoxy -O bond by nucleophilic substitution halide anion ionic liquids under mild conditions. Combined with hydrogenation over Pd/C, 1-butyl-2,3-dimethylimidazolium bromide can realize deconstruction various including...
Chemical transformation of spent polyesters into value-added chemicals is substantial for sustainable development but still challenging. Here, we report a simple, metal-free, and efficient aminolysis strategy to upcycle polylactic acid by anilines over lactate-based ionic liquids (e.g., tetrabutylammonium lactate), accessing series N-aryl lactamides under mild conditions. This also effective degradation poly(bisphenol A carbonate), affording bisphenol corresponding diphenylurea derivatives....
Abstract The chemical transformation of waste polymers into value-added chemicals is significance for circular economy and sustainable development. Herein, we report upcycling poly(succinates) (PSS) with amines N-substituted succinimides over succinimide anion-based ionic liquids (ILs, e.g, 1,8-diazabicyclo[5.4.0]undec-7-ene succinimide, [HDBU][Suc]). Assisted H 2 O, [HDBU][Suc]) showed the best performance, which could achieve complete a series PSS derivatives corresponding diols under mild...
Abstract Benzofuran derivatives can be synthesized through the sequential Michael addition and cyclization of 1,3‐dicarbonyl compounds with 1,4‐benzoquinones. However, ketones are rarely used in this reaction because their low nucleophilicities. In study, problem was solved by utilizing triethyl orthoformate, which enabled formation a vinyl ethyl ether as an additive. As result, nucleophilicity increased. Many important 5‐hydroxybenzofuran derivatives, were not readily available synthesis...

Abstract Benzo[α]carbazoles were synthesized from 2‐phenylindoles and α‐bromoacetaldehyde using bismuth trichloride as a catalyst. The reaction was triggered by trichloride‐catalyzed Friedel‐Crafts alkylation of these two precursors, which provided tryptaldehyde intermediate that underwent intramolecular olefination to form the final product. Interestingly, HBr byproduct generated in upstream step catalyzed following downstream steps, thus creating byproduct‐participated relay catalytic...
