Dilithium Enediamide Derived From 1,4‐Diaza‐1,3‐Diene: An Electron Reservoir Enabling Variable Reactivity Toward Carbonyl Compounds

European Journal of Inorganic Chemistry, Volume 29, Issue 21, 25 July 2026.
Upon reduction of 1,4‐diaza‐1,3‐diene 1 to the dilithium enediamide 2, the polarity of the C = N bonds is reversed ‐ a classic case of umpolung. This behavior is particularly evident in reactions of the dianion 2 with carbonyl compounds and also explains why 1,4‐diaza‐1,3‐diene ligands do not always act merely as spectator ligands. 1,4‐Diaza‐1,3‐dienes

Dilithium Enediamide Derived From a 1,4‐Diaza‐1,3‐diene: Reactivity of a Strongly N‐Basic, Highly C‐Nucleophilic Compound Toward C–H Acids

European Journal of Inorganic Chemistry, Volume 29, Issue 20, 17 July 2026.
The lithium enediamide complex 2 with intrinsically inverted C–N bond polarity combines strong basicity with unusual reactivity: deprotonation of malonates enables C–C bond formation without electron transfer. Depending on malonate substitution, electrophilic substitution or addition occurs at the enediamide CC bond.

Si─Si Bonding in an Unsupported N‐Heterocyclic Silylene Dimer Stabilized by an Iminophosphorane‐Based Scorpionate Ligand Versus Head‐to‐Tail Coordination in the Sn and Pb Tetrylenes

Chemistry – A European Journal, Volume 32, Issue 25, 2 July 2026.
A new iminophosphorane‐based scorpionate ligand enabled the characterization of a head‐to‐head silylene dimer with unsupported Si─Si bonding, whereas the tetrylene species of Sn and Pb afforded head‐to‐tail coordination polymers in the solid state. ABSTRACT N,N‐chelating ligands disfavor element–element bonding in heavier alkene analogs of group 13 and

Finding a polytope: A practical fault attack against Dilithium [PDF]

In Dilithium, the rejection sampling step is crucial for the proof of security and correctness of the scheme. However, to our knowledge, there is no attack in the literature that takes advantage of an attacker knowing rejected signatures. The aim of this

Electrolyte‐Dependent Aging Analysis in SiOx‐Based Li‐Ion Batteries via Composite Electrode Model

Batteries &Supercaps, Volume 9, Issue 7, July 2026.
Electrolyte‐dependent aging of SiOx anodes is clarified through combined experiments and physics‐based modeling. A pseudo‐two‐dimensional model explicitly couples electrolyte consumption with binary solid electrolyte interphase growth. The model predicts fluoroethylene carbonate‐dependent lithium loss, overpotential increase, and capacity fade ...
