Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

Chemistry – A European Journal, EarlyView.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...

A complete identification of lithium sites in a model of LiPO$_3$ glass: effects of the local structure and energy landscape on ionic jump dynamics

, 2004
We perform molecular dynamics simulations to study lithium dynamics in a model of LiPO$_3$ glass at temperatures below the glass transition. A straightforward analysis of the ionic trajectories shows that lithium diffusion results from jumps between ...

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

Chemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

Dark Matter Constraints in Heterotic M-Theory with Five-Brane Dominance [PDF]

, 2001
The phenomenological implications of the M-theory limit in which supersymmetry is broken by the auxiliary fields of five-brane moduli is investigated. Assuming that the lightest neutralino provides the dark matter in the universe, constraints on the ...

Substituent‐Controlled Ring Opening of 1‐Substituted Benzocyclobutenes: Electronic Structure and Diradical Character of Ortho‐Quinodimethane Intermediates

Chemistry – A European Journal, EarlyView.
Experimental and computational studies elucidate how the electronic nature of substituents controls the ring‐opening temperature and diradical character of 1‐substituted benzocyclobutenes, enabling the rational design of o‐quinodimethane‐based synthetic transformations.

Alkyl Bismuth Cations: Synthesis, Characterization, and Application as Z‐Type Ligands

Chemistry – A European Journal, EarlyView.
Rare examples of alkyl bismuth cations [BiR2(SbF6)] are presented, including cyclopropyl ligands and a bismacyclic structure. The bismuth‐centered Lewis acids act as Z‐type ligands toward the electron‐rich platinum atom in [Pt(PCy3)2], generating a set of metal‐only Lewis pairs. The structural and spectroscopic properties of these rare types of bismuth
