Plastic waste could become a CO2 sponge through amine chemistry

Aarhus University researchers upcycled discarded polystyrene into a solid amine-based carbon-capture material that works at both smokestack CO2 concentrations and ambient air; a two‑step bromination (gold catalyst) and amination (copper catalyst) builds a tunable porous structure, showing potential to derive carbon-capture materials from waste plastics, though energy use and performance trade-offs remain.

Revolutionary Chemistry Discovery Promises Major Advances in Medicine and Agriculture

Scientists at the Technion have developed triazenolysis, a novel chemical process that converts alkenes into multifunctional amines, offering significant advancements in polymer, pharmaceutical, and agricultural production. Unlike the traditional ozonolysis, which forms carbon-oxygen bonds, triazenolysis efficiently creates carbon-nitrogen bonds, enhancing its applicability across various fields. This breakthrough, detailed in Nature Chemistry, was achieved by a team led by Prof. Mark Gandelman and supported by the Israel Science Foundation.

Cu-catalyzed N-alkylation of aliphatic amines with enantioconvergence.

Researchers have developed a new method for the enantioselective N-alkylation of aliphatic amines with α-carbonyl alkyl chlorides using chiral tridentate anionic ligands and copper catalysts. The method can convert feedstock chemicals, including ammonia and pharmaceutically-relevant amines, into unnatural chiral α-amino amides under mild and robust conditions with excellent enantioselectivity and functional group tolerance. The method has potential applications in the expedited synthesis of diverse amine drug molecules.
