TL;DR: The concentrations of individual PFASs in air, outdoor settled dust, and surface river water decreased exponentially as the distance increases from the FMPs, whereas the concentrations of short-chain perfluoroalkyl carboxylic acids (PFCAs) remained high in the surface water 38 km away.

Silver-catalyzed C-H trifluoromethylation of arenes using trifluoroacetic acid as the trifluoromethylating reagent.
TL;DR: This reaction not only provides a new protocol for aryl C-H trifluoromethylation, but the generation of CF3· from TFA may prove useful in other contexts and could potentially be extended to other triffluorometHylation reactions.

A novel process for recycling and resynthesizing LiNi1/3Co1/3Mn1/3O2 from the cathode scraps intended for lithium-ion batteries.
TL;DR: Electrochemical tests show that the initial charge and discharge capacities of the resynthesized LiNi1/3Co 1/3Mn1/ 3O2 are 201 mAh g(-)(1) and 155.4 m Ah g(-1) (2.8-4.5 V, 0.1C), respectively.

Hydrosilane reduction and 1,5-hydride transfer in the [2-(3-ethoxythienyl)]di(1-adamantyl)methyl cation
John S. Lomas,Edouard Vauthier +1 more
TL;DR: In this article, the carbocation formed by reaction of anti-[2-(3-ethoxythienyl)]di(1-adamantyl)methanol with trifluoroacetic acid (TFA) in dichloromethane is reduced by hydrosilanes, to give both syn and anti-isomer, but also undergoes an intramolecular 1,5-hydride shift to give a carboxonium ion, reduction of which gives the anti isomer.

Fluorinated Acetic Acids
TL;DR: Fluoroacetic acid is a carboxylic acid with slightly higher than average acidity that undergoes reactions typical of acetic acid as discussed by the authors, it is conveniently prepared by reaction of fluoride ion with chloro- or bromo-acetic acids esters, followed by ester hydrolysis It is extremely toxic and its sodium salt is one of the most effective allpurpose rodenticides known.

Trifluoroacetic acid: a unique solvent for atom transfer radical cyclization reactions
Tao Wu,Hui Yu,Chaozhong Li +2 more
TL;DR: Triethylborane-initiated atom transfer radical cyclization reactions of various allyl or 3-butenyl iodoacetates could be efficiently carried out at room temperature with trifluoroacetic acid as the solvent as discussed by the authors.

Some cation-induced bicyclisations
TL;DR: Cyclisations of the enones and the related epoxides have been investigated and shown to give tetra-and tri-cyclic compounds in variable yield as discussed by the authors, which is the state-of-the-art.
