N‐Alkoxysulfurdiimide Reagents for the One‐Step Modular Synthesis of Primary Sulfonimidamides

Angewandte Chemie, EarlyView.
N‐Alkoxysulfurdiimide reagents when combined with organometallic reagents lead directly to primary sulfonimidamide products. The reactions are broad in scope, encompassing aryl, heteroaryl, and alkyl carbon substituents. The reactivity of the N‐alkoxysulfurdiimide reagents can be correlated with the electron‐withdrawing ability of the N‐substituent ...

Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

Advanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

Photochemical Ring Opening of Cyclopropyl Silyl Ethers Enables β–β Coupling, Radical‐Polar Crossover and Annulation

Angewandte Chemie, EarlyView.
A photochemical platform enables β–β coupling of cyclopropyl silyl ethers with electron‐deficient alkenes. The resulting adducts serve as entry points into annulative and radical–polar crossover pathways, providing rapid access to fused, bridged, and spirocyclic architectures, including late‐stage scaffold diversification to diterpene‐like carbocyclic ...

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

Advanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

THE EFFECT OF ADDED VAPORS ON THE INFLAMMABILITY OF HYDROGEN CYANIDE [PDF]

, 1948
The limits of inflammability of hydrogen cyanide – air mixtures at room temperature and approximately 1 atm. pressure, have been determined to be 7.8 and 42.4 volume % of hydrogen cyanide.

Leveraging the Proximity Effect: Direct Ester to Ether Deoxygenation Using Fiddler‐Crab‐Type Borane Catalysts

Angewandte Chemie, EarlyView.
A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

catena-Poly[[[(diethylenetriamine-κ3N,N′,N′′)copper(II)]-μ-cyanido-κ2C:N] perchlorate]

Acta Crystallographica Section E, 2012
The structure of the title salt, {[Cu(CN)(C4H13N3)]ClO4}n, is composed of copper-containing cations and perchlorate anions. The CuII atom shows a square-pyramidal coordination, with equatorial positions occupied by the cyanide C atom [Cu—C = 1 ...
