Blue Emitting Star-Shaped and Octasilsesquioxane-Based Polyanions Bearing Boron Clusters. Photophysical and Thermal Properties

Molecules, 2020
High boron content systems were prepared by the peripheral functionalisation of 1,3,5-triphenylbenzene (TPB) and octavinylsilsesquioxane (OVS) with two different anionic boron clusters: closo-dodecaborate (B12) and cobaltabisdicarbollide (COSAN). TPB was

Photolysis of Diborane at 1849 Å [PDF]

, 1962
The photolysis of diborane at 1849 Å has been studied in a specially constructed, internal‐type mercury‐vapor lamp. The products have been found to be H_2, B_(4)H_(10), B_(5)H_(11), and, at low pressures, a —BH— polymer.

NHC-Boranes: Air- and Water-tolerant Co-initiators for Type II Photopolymerizations

CHIMIA, 2012
N-Hetereocyclic carbene (NHC) complexes of boranes are stable compounds that can be used as co-initiators for the type II photopolymerization of acrylates.

DFT Investigation of Hydrogen Atom Abstraction from NHC-Boranes by Methyl, Ethyl and Cyanomethyl Radicals—Composition and Correlation Analysis of Kinetic Barriers

Molecules, 2020
Understanding the hydrogen atom abstraction (HAA) reactions of N-heterocyclic carbene (NHC)-boranes is essential for extending the practical applications of boron chemistry.

Novel B(Ar')2(Ar'') hetero-tri(aryl)boranes: a systematic study of Lewis acidity [PDF]

, 2016
A series of homo- and hetero-tri(aryl)boranes incorporating pentafluorophenyl, 3,5-bis(trifluoromethyl)phenyl, and pentachlorophenyl groups, four of which are novel species, have been studied as the acidic component of frustrated Lewis pairs for the ...

Construction of boron-stereogenic compounds via enantioselective Cu-catalyzed desymmetric B–H bond insertion reaction

Nature Communications, 2022
Enantioselective catalytic methods for the construction of boron-stereogenic compounds are elusive. In this article, the authors describe a route to these compounds via a copper-catalysed desymmetric B-H insertion on 2-arylpyridine-boranes with carbenes.

Redox Targets for Phosphine–Boranes

Inorganics, 2023
Understanding the complex mechanisms underlying redox-mediated biological processes is a fundamental pillar of cellular biology. We describe the identification and quantification of disulfide formation and reduction in response to phosphine–borane ...

Could humans recognize odor by phonon assisted tunneling? [PDF]

, 2006
Our sense of smell relies on sensitive, selective atomic-scale processes that are initiated when a scent molecule meets specific receptors in the nose. However, the physical mechanisms of detection are not clear.

The topological uniqueness of the deltahedra found in the boranes BnHn2− (6≤n≤12) [PDF]

, 1990
The deltahedra observed experimentally in the borane anions BnHn2− (6≤n≤12) are the only possible n-vertex deltahedra having only degree 4 and 5 vertices.

Ambiphilic boron in 1,4,2,5-diazadiborinine

Nature Communications, 2016
Boranes are archetypal Lewis acids owing to an empty p-orbital on the boron, although Lewis basic tricoordinate boranes have been developed too. Here, the authors report an annulated 1,4,2,5-diazadiborinine derivative with boron atoms that exhibit both ...
