“Activated Borane” – A Porous Borane Cluster Network [PDF]

, 2022
The unprecedented co-thermolysis of nido-decaborane (B10H14) and toluene results in a novel porous material (that we have named “Activated Borane”) containing micropores of 1.0 and 1.5 nm in diameter and a specific surface area of 774 m2 g-1 (Ar, 87 K) that is thermally stable up to 1000 oC.

A borane laser [PDF]

Nature Communications, 2015
Emission from electronically excited species forms the basis for an important class of light sources-lasers. So far, commercially available solution-processed blue-emitting laser materials are based on organic compounds or semiconductor nanocrystals that have significant limitations: either low solubility, low chemical- and/or photo-stability and/or ...

Catalytic Dehydrogenation of Amine‐Boranes using Geminal Phosphino‐Boranes [PDF]

Zeitschrift für anorganische und allgemeine Chemie, 2020
The reaction of the intramolecular frustrated Lewis pair (FLP) tBu2PCH2BPh2 with the amine‐boranes NH3·BH3 and Me2NH·BH3 leads to the formation of the corresponding FLP‐H2 adducts as well as novel five‐membered heterocycles that result from capturing the in situ formed amino‐borane by a second equivalent of FLP.

Boranes in Organic Chemistry 1. О±-Carbonylalkyl- and ОІ-Oxyalkylboranes in Organic Synthesis

Eurasian Chemico-Technological Journal, 2002
This review is devoted to the synthesis of a-carbonylalkyl- and ОІ-hydroxy-alkyl boranes and their use in organic synthesis. a-Carbonyl-alkylboranes include several heteroatomic compounds, in particular, [1.2.3]-diazaborinines, uracyl boronic acids, and [

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 ...

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

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.

Diastereoselective three-component synthesis of beta-amino carbonyl compounds using diazo compounds, boranes, and acyl imines under catalyst-free conditions [PDF]

, 2014
Diazo compounds, boranes, and acyl imines undergo a three-component Mannich condensation reaction under catalyst-free conditions to give the anti β-amino carbonyl compounds in high diastereoselectivity.
