Atroposelective Access to π‐Conjugated 1,2‐Azaborepines Enabled by Palladium‐Catalyzed Cyclization of N‐Heterobiaryls with Alkynylboronates

Advanced Science, EarlyView.
We report a palladium‐catalyzed atroposelective cyclization of N‐heterobiaryl triflates with alkynyl boronates to access seven‐membered 1,2‐BN‐bridged biaryls with high yields and excellent enantioselectivity via a cascade DyKAT, cis‐carbopalladation, and 1,2‐migration, which expands the toolbox for axially chiral π‐conjugated boron compounds and opens

Understanding the Catalytic Determinant role of Diaphorase‐Like Subunit in Formate Dehydrogenases via Redox Couples

Advanced Science, EarlyView.
A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...

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

Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

Advanced Science, EarlyView.
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...

Aromaticity‐Engineered Open‐Shell Radical Anions for Air‐Stable Doublet Emission in N‐Annulated Perylene Diimide

Advanced Science, EarlyView.
Open‐shell type radical anions with stable doublet emission have been synthesized that feature aromaticity engineering, through‐space charge‐transfer (TSCT), and electro(fluoro)chromism. ABSTRACT We report the doublet emissive open‐shell radical anions, where the N‐annulated perylene diimide (PDIN–H) is functionalized with aromatic rings.
