AI Article Synopsis

  • Researchers successfully developed a method for defluoroborylating polyfluoroarenes using photoredox catalysis at room temperature.
  • The process involves generating a boryl radical through a single-electron transfer (SET) and shows high regioselectivity and functional group tolerance.
  • Both computational and experimental approaches were utilized to better understand the reaction mechanism behind this innovative technique.

Article Abstract

The first photoredox-catalyzed defluoroborylation of polyfluoroarenes with NHC-BH has been facilely achieved at room temperature via a single-electron-transfer (SET)/radical addition pathway. This new strategy makes full use of the advantage of photoredox catalysis to generate the key boryl radical via direct activation of a B-H bond. Good functional group tolerance and high regioselectivity offer this protocol incomparable advantages in preparing a wide array of valuable polyfluoroarylboron compounds. Moreover, both computational and experimental studies were performed to illustrate the reaction mechanism.

To provide fluorinated allylamines, a visible-light photocatalytic C-F/C-H coupling of easily accessible -difluoroalkenes and secondary -alkylanilines was described. The protocol proceeded under mild conditions, with excellent functional group compatibility and a broad scope including complex natural product derivatives, thus providing a green method for the preparation of high-value functionalized monofluoroalkenes. Mechanistic studies elucidated a photoredox catalyzed radical-radical coupling pathway.

Photocatalytic low-temperature defluorination of PFASs.

Nature

November 2024

Hefei National Research Center for Physical Sciences at the Microscale, Department of Chemistry, University of Science and Technology of China, Hefei, China.

Polyfluoroalkyl and perfluoroalkyl substances (PFASs) are found in many everyday consumer products, often because of their high thermal and chemical stabilities, as well as their hydrophobic and oleophobic properties. However, the inert carbon-fluorine (C-F) bonds that give PFASs their properties also provide resistance to decomposition through defluorination, leading to long-term persistence in the environment, as well as in the human body, raising substantial safety and health concerns. Despite recent advances in non-incineration approaches for the destruction of functionalized PFASs, processes for the recycling of perfluorocarbons (PFCs) as well as polymeric PFASs such as polytetrafluoroethylene (PTFE) are limited to methods that use either elevated temperatures or strong reducing reagents.

Organic halides are highly useful compounds in chemical synthesis, where the halide serves as a versatile functional group for elimination, substitution, and cross-coupling reactions with transition metals or photocatalysis. However, the activation of carbon-fluorine bonds, the most commercially abundant organohalide and found in PFAS, or "forever chemicals", are much rarer. Current approaches based on photoredox chemistry for activation of small molecule carbon-fluorine (C-F) bonds are limited by the substrates and transition-metal catalysts needed.

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are persistent compounds characterized by stable C-F bonds giving them high thermal and chemical stability. Numerous studies have highlighted the presence of PFASs in the environment, surface waters and animals and humans. Exposure to these chemicals has been found to cause various health effects and has necessitated the need to develop methods to remove them from the environment.

Ecotoxicological risk assessment on coagulation-flocculation in water/wastewater treatment: a systematic review.

Environ Sci Pollut Res Int

Faculty of Chemical and Energy Engineering, Universiti Teknologi Malaysia, 81310, Skudai, Johor, Malaysia.

It is undeniable that removal efficiency is the main factor in coagulation-flocculation (C-F) process for wastewater treatment. However, as far as environmental safety is concerned, the ecotoxicological aspect of the C-F process needs to be examined further. In this study, a systematic review was performed based on publications related to the toxicity research in C-F technology for wastewater treatment.
