Where Does the Fluorine Come From? A Review on the Challenges Associated with the Synthesis of Organofluorine Compounds
TL;DR: In this article, the supply chain to access the necessary raw materials, which is critical for a variety of applications, including pharmaceutical products, is discussed. And the authors propose a solution to this problem.

Multimedia Distribution and Transfer of Per- and Polyfluoroalkyl Substances (PFASs) Surrounding Two Fluorochemical Manufacturing Facilities in Fuxin, China.
Hao Chen,Yiming Yao,Zhen Zhao,Yu Wang,Qi Wang,Chao Ren,Bin Wang,Hongwen Sun,Alfredo C. Alder,Kurunthachalam Kannan +9 more
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.

Comparison of 55% TFA/CH2Cl2 and 100% TFA for Boc group removal during solid-phase peptide synthesis.
TL;DR: Volumetric measurements showed that the omission analogs generated are probably due to insufficient swelling of the resin, resulting in limited solvent transfer of 100% TFA into the resin and, in turn, incomplete Boc removal.

Non-defluorinative electrochemical silylation of ethyl trifluoroacetate: a practical synthesis of trifluoroacetyltrimethylsilane via its ethyltrimethylsilyl ketal
TL;DR: In this article, an efficient method for the preparation of original trifluoroacetyltrimethylsilane, CF 3 COSiMe 3 ( 3 ), in two steps from readily available ethyl trfluroacetate is described.

Trifluoroacetylation of arylamines using poly-phosphoric acid trimethylsilylester (PPSE)
TL;DR: In this paper, a trifluoroacetylation of arylamines using polyphosphoric acid trimethylsilylester (PPSE) as the condensation agent is described.

Directing abilities of alcohol-derived functional groups in the hydroformylation of olefins.
Li Ren,Cathleen M. Crudden +1 more
TL;DR: It is suggested that inherent conformational preferences are of significant importance in determining the product distribution and that the directing power of simple alcohols and their derivatives is moderate at best under the conditions examined in this study.
