A Reductive Mechanochemical Approach Enabling Direct Upcycling of Fluoride from Polytetrafluoroethylene (PTFE) into Fine Chemicals

This paper presents a new mechanochemical method to break down Polytetrafluoroethylene (PTFE), commonly known as Teflon, using sodium metal and ball milling at room temperature, converting it into sodium fluoride and elemental carbon with 98% efficiency. The recovered fluoride can then be directly used to synthesize valuable sulfonyl fluoride and acyl fluoride fine chemicals through in situ mechanochemical fluorination reactions, offering a more sustainable way to recycle fluorine from PTFE waste.

Total Synthesis of the Nominal Structure of (+)-Talaromyolide D

This study describes the first total synthesis of what was thought to be (+)-talaromyolide D, a molecule found in a marine fungus. However, comparison of the lab-made molecule and the natural product revealed that the original structure was misassigned. This synthesis now offers a path to determine the correct structure of the natural product and to make enough to test its antiviral properties.

A simple and versatile nickel platform for the generation of branched high molecular weight polyolefins

This paper describes a new type of nickel catalyst based on a-imino-ketone ligands, which is highly active in ethylene polymerization, producing branched high molecular weight polyethylene, including ultra-high-molecular-weight polyethylene. The catalysts are also capable of copolymerizing ethylene with a variety of polar monomers and can be easily supported on silica, forming a highly active heterogeneous catalyst.
