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.

A novel class of tunable zinc reagents (RXZnCH2Y) for efficient cyclopropanation of olefins.
TL;DR: A reasonable level of enantioselectivity was obtained for the cyclopropanation of unfunctionalized olefins when a chiral (iodomethyl)zinc species was used, providing a valuable approach for the asymmetric cyclopromation of uncoupled oleFins.

Removal of t-butyl and t-butoxycarbonyl protecting groups with trifluoroacetic acid. Mechanisms, biproduct formation and evaluation of scavengers.
TL;DR: In this paper, scavengers of sulphide structure react with t-butyl trifluoroacetate to form sulphonium compounds, which possess alkylating properties, and they are evaluated in the evaluation of scavengers.
