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 ...

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.

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, EarlyView.
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

The Future of Foundation Machine Learning Potentials and DFT in Homogeneous Catalysis: Competition or Synergy?

Chemistry – A European Journal, EarlyView.
Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

Novel Schiff Bases of Pyrrole: Synthesis, Experimental and Theoretical Characterizations, Fluorescent Properties and Molecular Docking [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2018
Some new Schiff-base compounds based on pyrrole were synthesized by the reaction of 2-amino-1-methyl-4,5-diphenyl-1H-pyrrole-3-carbonitrile (1)with aromatic aldehydes (2a-2e) in ethanol/acetic acid at room temperature.

Combination therapy with normobaric oxygen (NBO) plus thrombolysis in experimental ischemic stroke

BMC Neuroscience, 2009
Background The widespread use of tissue plasminogen activator (tPA), the only FDA-approved acute stroke treatment, remains limited by its narrow therapeutic time window and related risks of brain hemorrhage.

Alkali‐Metal Base Catalyzed Electrocyclization of Isoprene Derivatives

Chemistry – A European Journal, EarlyView.
Simple and abundant alkali‐metal base catalysis in combination with Lewis basic polyamines enables the electrocyclization of isoprene‐derived trienes to cycloheptadienes under neat conditions. Mechanistic insight supported by DFT guides a scalable route to seven‐membered carbocycles which, after reduction, give saturated cycloalkanes relevant as ...

Dinuclear Copper(I) Complexes Featuring Metal–Metal Interactions and a μ2‐Bridging Phosphane With Additional Olefinic Binding Sites

Chemistry – A European Journal, EarlyView.
A Cu2P triangle captured in a tetrapodal phosphane tris(olefin) ligand, where all binding forces are weak apart from the Cu─P interaction. ABSTRACT The molecule Ptrop3 contains in each trop unit (trop = dibenzo[a,d]cyclohepten‐5‐yl) a rigid central seven‐membered ring with an olefinic binding site making Ptrop3 potentially a tetradentate ligand ...

Gallein, a Gβγ subunit signalling inhibitor, inhibits metastatic spread of tumour cells expressing OR51E2 and exposed to its odorant ligand

BMC Research Notes, 2017
Objective We previously reported that the olfactory receptor OR51E2, overexpressed in LNCaP prostate cancer cells, promotes cell invasiveness upon stimulation of its agonist β-ionone, and this phenomenon increases metastatic spread.
