Transformations of Group 7 Carbonyl Complexes: Possible Intermediates in a Homogeneous Syngas Conversion Scheme [PDF]

open access: yes, 2009
A variety of C−H and C−C bond forming reactions of group 7 carbonyl complexes have been studied as potential steps in a homogeneously catalyzed conversion of syngas to C_(2+) compounds.

A combined "electrochemical-frustrated Lewis pair" approach to hydrogen activation: surface catalytic effects at platinum electrodes [PDF]

open access: yes, 2014
Herein, we extend our “combined electrochemical–frustrated Lewis pair” approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical–frustrated Lewis pair (FLP) system involving the B(C6F5)3 ...

Efficient Synthesis of an Aluminum Amidoborane Ammoniate

open access: yesEnergies, 2015
A novel species of metal amidoborane ammoniate, [Al(NH2BH3)63−][Al(NH3)63+] has been successfully synthesized in up to 95% via the one-step reaction of AlH3·OEt2 with liquid NH3BH3·nNH3 (n = 1~6) at 0 °C.

Search for D-D Fusion initiated by Nuclear Hotspots in Boranes [PDF]

open access: yesEPJ Web of Conferences, 2023
In the group of boron hydrogen compounds, decaborane and aminoborane belong to those with a particularly high hydrogen density in the molecular volume. Almost 100% of the protons in the molecule can be replaced by deuterons.

Spontaneous dehydrocoupling in peri-substituted phosphine-borane adducts [PDF]

open access: yes, 2016
This work was financially supported by the EPSRC and COST action CM1302 SIPs.Bis(borane) adducts Acenap(PiPr2·BH3)(PRH·BH3) (Acenap = acenaphthene-5,6-diyl; 4a, R = Ph; 4b, R = ferrocenyl, Fc; 4c, R = H) were synthesised by the reaction of excess H3B ...

Combining Two Types of Boron in One Molecule (To the 60th Anniversary of the First Synthesis of Carborane)

open access: yesChemistry, 2023
This review is an attempt to bring together the data from the literature on the synthesis and properties of icosahedral carborane derivatives, in which exo-polyhedral three- and four-coordinated boron substituents are attached directly to the carborane ...

Access to cationic polyhedral carboranes via dynamic cage surgery with N-heterocyclic carbenes

open access: yesNature Communications, 2021
In comparison to their neutral or anionic counterparts, examples of cationic boron clusters remain scarce. Here, the authors prepare a variety of cationic polyhedral boranes by reacting closo-10-vertex carboranes with N-heterocyclic carbenes; the ...

Copper-catalyzed radical trans-selective hydroboration of ynamides with N-heterocyclic carbene boranes

open access: yesiScience, 2022
Summary: Vinylboron compounds are important compounds in organic chemistry and biology. In this communication, we developed a copper(I)-catalyzed, highly regio- and stereoselective radical trans-hydroboration of ynamides with N-heterocyclic carbene (NHC)-

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

open access: yes, 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.

(Phosphanyl)phosphaketenes as building blocks for novel phosphorus heterocycles. [PDF]

open access: yes, 2017
Although BH3 simply coordinates the endocyclic P of (phospholidino)phosphaketene 1Dipp , the bulkier B(C6F5)3 gives rise to a zwitterionic diphosphirenium, which is a novel type of 2π-electron aromatic system as shown by the calculated NICS values. While
