Introducing the Cis‐2,3‐Bis(trifluoromethyl)cyclopropyl Chemotype: Late‐Stage Installation and Stereoelectronic Properties

ChemistryEurope, EarlyView.
The cis‐2,3‐bis(trifluoromethyl)cyclopropyl chemotype is introduced. The steric demand of this motif is intermediate between that of the heptafluoroisopropyl and prefluorotertbutyl groups; yet, it induces significantly less lipophilicity than these due to its facial polarity.

From Two‐Electron to Four‐Electron System: Electrolyte Regulation for Advanced Aqueous Zn–I2 Batteries

Carbon Energy, EarlyView.
This review systematically summarizes recent progress in electrolyte‐regulated aqueous Zn–I2 batteries (AZIBs). It outlines the fundamentals of AZIBs along with their main challenges, and then analyzes electrolyte‐engineering strategies that improve both two‐ and four‐electron reactions.

A Review on Applications and Challenges of Fullerenes in Proton Exchange Membranes

Carbon Energy, EarlyView.
This review is devoted to the analysis of the use of fullerenes and their functionalized derivatives to improve the efficiency of proton exchange membranes. The synthetic methods, structure, properties, and proton transfer mechanisms of fullerene‐containing membranes are discussed in detail. Promising areas of scientific research are discussed, and key

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

AgBF4‐Induced Site‐Selective Synthesis of 4‐Sulfonylindoles in Au‐Catalyzed Cyclization‐Sulfonyl Migration Reactions

Chemistry – A European Journal, EarlyView.
Site‐selective synthesis 4‐suflonylindoles was achieved by a cyclization‐rearrangement strategy by π‐Lewis acidic gold catalysts and the aid of silver cocatalyst. Particularly, the use of 3 equivalents of AgBF4 to SPhosAuCl is crucial for C4‐selective migration of the sulfonyl group.
