Photocatalytic Synthesis of Pentafluorosulfanyl Ketones, Acetals, and BCP Motifs Utilizing SF6

Advanced Science, EarlyView.
A photocatalytic single electron reduction strategy is reported for the activation and valorization of sulfur hexafluoride (SF6), a potent greenhouse gas. Under mild conditions, SF6 is reduced to generate pentafluorosulfanyl (SF5) radicals, enabling direct access to pentafluorosulfanyl ketones, acetals, and BCP motifs.

Role of benzyl ether in the inversion of reactivities in Friedel-Crafts benzylation of toluene by benzyl chloride and benzyl alcohol

, 1996
In the inversion in the reactivities and selectivities of benzyl chloride (BnCl) and benzyl alcohol (BnOH) in a single pot Friedel-Crafts benzylation with toluene, there is not only a preferential adsorption of benzyl alcohol on the solid acid catalyst ...

Programmable Solid‐Electrolyte Interfaces for Efficient and Selective Electrochemical Hydrogenations

Angewandte Chemie, EarlyView.
Poly(ionic liquid) binders are shown to actively control the electrode microenvironment, strongly enhancing electrochemical hydrogenation compared to traditional binders. The work redefines the binder as an active component of catalytic electrode design, reshaping local potential gradients and interfacial ion distribution to modulate adsorbed H ...

Backbone‐Length‐Optimized Inhibitors Deliver Long‐Retention Selectivity in Area‐Selective ALD of VO2

Advanced Science, EarlyView.
Area‐selective VO2 ALD is found to depend critically on inhibitor backbone length, which governs physisorption, chemisorption stability, and packing efficiency in a coupled manner. An intermediate backbone‐length achieves the best long‐retention selectivity, establishing a chemically and geometrically grounded design principle for small‐molecule ...

A Strong Lewis Acidic Diethylsilylium Catalyst for Direct Sulfonamidation of Challenging Ketones

Advanced Science, EarlyView.
Low‐substitution‐order silylium ions (R2HSi+) exhibit exceptional Lewis acidic activity. We report diethylsilylium‐catalyzed reductive sulfonamidation of functionalized ketones to access β‐amino esters. The in situ generated ion pair shows enhanced reactivity, with diethylsilane serving as both reductant and precatalyst. The developed protocol proceeds

Wet Transfer of In Situ Grown Azo‐Containing Two‐Dimensional Conjugated Covalent Organic Framework Films for Photoswitchable Electronic Devices

Angewandte Chemie, EarlyView.
Wet transfer of an atomically flat azo‐functionalized 2D covalent organic framework film onto monolayer MoS2 enables clean van der Waals heterostructure devices with reversible photoswitching and multilevel nonvolatile memory. ABSTRACT Two‐dimensional π‐conjugated covalent organic frameworks (2D π‐COFs) combine in‐plane π‐delocalization with periodic ...
