Electrochemical Late-Stage Functionalization

Chemical Reviews, Год журнала: 2023, Номер 123(19), С. 11269 - 11335

Опубликована: Сен. 26, 2023

Late-stage functionalization (LSF) constitutes a powerful strategy for the assembly or diversification of novel molecular entities with improved physicochemical biological activities. LSF can thus greatly accelerate development medicinally relevant compounds, crop protecting agents, and functional materials. Electrochemical synthesis has emerged as an environmentally friendly platform transformation organic compounds. Over past decade, electrochemical late-stage (eLSF) gained major momentum, which is summarized herein up to February 2023.

Degradation of Polyacrylates by One-Pot Sequential Dehydrodecarboxylation and Ozonolysis

Journal of the American Chemical Society, Год журнала: 2023, Номер 145(19), С. 10480 - 10485

Опубликована: Май 8, 2023

We establish a synthetically convenient method to degrade polyacrylate homopolymers. Carboxylic acids are installed along the polymer backbone by partial hydrolysis of ester side chains, and then, in one-pot sequential procedure, carboxylic converted into alkenes oxidatively cleaved. This process enables robustness properties polyacrylates be maintained during their usable lifetime. The ability tune degree degradation was demonstrated varying acid content polymers. is compatible with wide range polymers prepared from vinyl monomers through copolymerization acrylic different including acrylates, acrylamides, styrenics.

From Plastic Waste to Treasure: Selective Upcycling through Catalytic Technologies

Advanced Energy Materials, Год журнала: 2023, Номер 13(41)

Опубликована: Сен. 24, 2023

The huge amount of plastic wastes has become a pressing global environmental problem, leading to severe pollution and resource depletion through conventional downcycling technologies like incineration landfilling. In contrast, selective upcycling various plastics offers promising solution for converting waste into valuable products. This review provides comprehensive overview the recent advancements in innovative catalytic technologies, including thermocatalysis, electrocatalysis, photocatalysis. Special emphasis is placed on elucidating reaction mechanisms, activating designated chemical bonds high selectivity, elaborating above techniques terms conditions Finally, application prospects future development trends catalysis are discussed, providing insights realizing sustainable circular economy.

Catalytic Upcycling of Polyolefins

Chemical Reviews, Год журнала: 2024, Номер 124(16), С. 9457 - 9579

Опубликована: Авг. 16, 2024

The large production volumes of commodity polyolefins (specifically, polyethylene, polypropylene, polystyrene, and poly(vinyl chloride)), in conjunction with their low unit values multitude short-term uses, have resulted a significant pressing waste management challenge. Only small fraction these is currently mechanically recycled, the rest being incinerated, accumulating landfills, or leaking into natural environment. Since are energy-rich materials, there considerable interest recouping some chemical value while simultaneously motivating more responsible end-of-life management. An emerging strategy catalytic depolymerization, which portion C-C bonds polyolefin backbone broken assistance catalyst and, cases, additional molecule reagents. When products molecules materials higher own right, as feedstocks, process called upcycling. This review summarizes recent progress for four major upcycling strategies: hydrogenolysis, (hydro)cracking, tandem processes involving metathesis, selective oxidation. Key considerations include macromolecular reaction mechanisms relative to mechanisms, design transformations, effect conditions on product selectivity. Metrics describing critically evaluated, an outlook future advances described.
