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 aromatic aliphatic ones, copolyesters polyester mixtures into corresponding carboxylic acids alkanes; meanwhile, tetrabutylphosphonium achieve direct decomposition β -H alkenes hydrogen- metal-free It found that hydrogen-bonding interaction between liquid ester group in enhances nucleophilicity activates bond.

The exploitation of carbon dioxide (CO2) as a sustainable, plentiful, and harmless C1 source for the catalytic synthesis enantioenriched carboxylic acids has long been acknowledged pivotal task in synthetic chemistry. Herein, we present current-driven nickel-catalyzed reductive carboxylation reaction with CO2 fixation, facilitating formation C(sp3)–C(sp2) bonds by circumventing handling moisture-sensitive organometallic reagents. This electroreductive protocol serves practical platform, paving way propargylic (up to 98% enantiomeric excess) from racemic carbonates CO2. efficacy this transformation is exemplified its successful utilization asymmetric total (S)-arundic acid, (R)-PIA, (S)-chizhine D, (S)-cochlearin G, (S,S)-alexidine, thereby underscoring potential electrosynthesis achieve complex molecular architectures sustainably.

This Viewpoint discusses the implications of net zero energy transition on traditional chemical feedstocks and catalytic elements. While full impact upcoming changes is difficult to assess, some trends from scenarios already underway can be mapped. For example, a steady growth in electric passenger vehicles will diminish transportation-related petroleum refining output, which could then create feedstock gaps supply/demand dynamics certain critical metals. These impacts present unexpected opportunities for emerging such as biomass, sequestered CO2, recycled carbon bridge supply gaps, even within next decade. Further, metals Pd, Rh, Pt displaced automotive exhaust converter applications potentially become more available producing chemicals aviation fuels feedstocks. At same time, Co Ni, are currently considered earth abundant, face increasing demand storage thus less attractive applications. The availability carbon-free hydrogen oxygen facilitate march toward decarbonization industry. Finally, enormity assets offers possibility repurposing them process disruptions have profound future catalysis research must well-guided industrial sustainability.
