Using waste poly(vinyl chloride) to synthesize chloroarenes by plasticizer-mediated electro(de)chlorination

Degradation of Polyacrylates by One-Pot Sequential Dehydrodecarboxylation and Ozonolysis

“…Polyacrylates are regularly used in a number of applications including packaging, paints, coatings, adhesives, and sealants. − One of the most attractive features of polyacrylates is their durability, which arises from their chemical stability. However, the robust nature of polymers with all-carbon backbones often leads to the accumulation and persistence of post-consumer polyacrylate waste in landfills or oceans. − Accordingly, it is projected that 11 billion metric tons of plastic waste will amass in the environment by 2025 . Although there are economic and environmental incentives for recycling, there are limited options for treating discarded plastics .…”

Upcycling of Polybutadiene Facilitated by Selenium‐Mediated Allylic Amination

“…Recently, strategies for the functionalization of polystyrene, [16] polyolefins, [17–20] polyethers, [21] polylactides, [22] and polyacrylates [23, 24] have evolved concurrently with the modernization of synthetic organic methodology [25] . Advances in C−H activation, [8] (photo)redox catalysis, [21, 26, 27] and organocatalysis [17, 18] have enabled the streamlined synthesis of previously inaccessible macromolecules from post‐consumer plastics.…”

“…Post-polymerization modification (PPM) of existing post-consumer plastic is a common approach to upcycle commodity materials [7][8][9][10][11] without needing to design novel monomers for depolymerization-repolymerization strategies. [12][13][14][15] Recently, strategies for the functionalization of polystyrene, [16] polyolefins, [17][18][19][20] polyethers, [21] polylactides, [22] and polyacrylates [23,24] have evolved concurrently with the modernization of synthetic organic methodology.

Electrochemical Late-Stage Functionalization

“…Yoshida introduced the concepts of electroauxiliaries and cation pool to increase the electrosynthesis viability in the late 20th century. − Meanwhile, Steckhan elegantly formalized the principles of indirect electrolysis, which thereafter brought forth numerous mediator-driven processes. , Subsequent key achievements on the direct electrolysis were made by Schäfer, Lund, Little, − Moeller, Jutand, and Amatore around the 21st century. On the basis of these pioneering contributions, electro-organic synthesis reemerged in the past decade, with major contributions by Baran, Xu, Lei, Ackermann, Lambert, Lin, Gouin, Waldvogel, Stahl, Malins, and Mei, among others. − Thus, major advances have been achieved in various fields, including C–H activation, reductive cross-electrophile coupling, alkene difunctionalization, nitrogen-centered radical mediated chemistry, total synthesis, and the LSF of natural products and medicinally relevant molecules (Scheme b).…”
