Interfacial Electron‐Modulated Pt Sites on Self‐Supported NiCoP Nanosheets for Enhancing Hydrogen Evolution Reaction

Carbon Energy, EarlyView.
Using a hierarchical multilevel‐structure strategy, we design and prepare a self‐supported Pt/NiCoP/CF catalyst with a strong electron transfer effect between Pt and NiCoP. This catalyst realizes highly efficient HER performance under full pH range, outperforming commercial Pt/C catalyst.

FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway

Chemistry – A European Journal, EarlyView.
Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

Bis(2‐Adamantyl)Magnesium: Synthesis, Structure, and Applications of a Versatile and Shelf‐Stable 2‐Adamantyl Anion Equivalent

Chemistry – A European Journal, EarlyView.
At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...

Electrochemical Fluorination of Partially Fluorinated Dialkylethers. Synthesis of Sevoflurane Derivatives (CF3)2CHOCHF2, (CF3)2CHOCF3, and (CF3)2CFOCF3

Chemistry – A European Journal, EarlyView.
Electrochemical fluorination (ECF, Simons process) is a valuable method for the fluorination of partially fluorinated dialkyl ethers, providing an inexpensive, scalable, and safe access to partially fluorinated ethers with a higher fluorine content and the perfluorinated analogues that are hardly accessible using other fluorination techniques ...
