A new method for the generation of trifluoromethylcopper ("CuCF3") species from readily available phenyl trifluoromethyl sulfoxide has been developed. The "CuCF3" reagent can be applied in efficient trifluoromethylations of aryl iodides and activated aryl bromides in the absence of additional ligands. Furthermore, the "CuCF3" species can also undergo oxidative cross-coupling with terminal alkynes and arylboronic acids.

The present review provides a comprehensive summary of the catalytic and catalyst-free diboration of alkynes.

To achieve superior solid-state lithium batteries, we have fabricated a flexible composite solid electrolyte (CSE) membrane composed of a poly(vinylidene fluoride) (PVDF) matrix, high-concentration lithium salt (LiTFSI), solvent (DMF), and ceramic filler Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP). A small quantity of polar solvent DMF can not only facilitate the dissociation of LiTFSI but also form lithium-rich complexes [Li(DMF) n TFSI] with Li + , which have the properties of ionic liquids and can improve ionic conductivity. Meanwhile, high-concentration LiTFSI provides a large number of free lithium ions, and TFSI − anions also aggregate to form ion clusters, which pass through the interconnecting network of the filler LATP to form a unique fast conduction channel. Thanks to the synergistic effect between the various components of the LATP-PVDF/Li CSE, the obtained CSE achieves a high ionic conductivity of 2.44 × 10 −4 S cm −1 (25 °C), an excellent electrochemical stability window of up to 4.8 V (vs Li + /Li), and desirable self-extinguishing ability. In addition, the CSE exhibits excellent lithium dendrite inhibition ability, which has been verified by periodic lithium stripping/plating tests for more than 3000 h. All of the assembled solid-state LiFePO 4 ||Li, LiCoO 2 ||Li, and LiNi 0.6 Co 0.2 Mn 0.2 O 2 ||Li cells exhibit distinguished rate performance and cycling stability at 30 °C. Furthermore, the LiFePO 4 ||Li solid-state pouch batteries also exhibit excellent flexibility and safety. This investigation demonstrates the importance of the synergistic strategy between the various components of the CSE and opens up ideas for the research and development of high-performance CSEs.
