Insertion of Carbenes into Deprotonated nido-Undecaborane, B₁₁H₁₃(2-)

Molecules, 2019
We have examined the insertion of carbenes carrying leaving groups into the [nido-B11H13]2− dianion to form the [closo-1-CB11H12]− anion. The best procedure uses CF3SiMe3 and LiCl as the source of CF2.

Synthesis of new representatives of A3B-type carboranylporphyrins based on meso-tetra(pentafluorophenyl)porphyrin transformations

Beilstein Journal of Organic Chemistry
A carboranylporphyrin of A3B-type bearing a single pentafluorophenyl ring was prepared through the regioselective nucleophilic aromatic substitution reaction of the p-fluorine atoms in 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin with 9-mercapto-m ...

Quantum-mechanical calculations of the stabilities of fluxional isomers of C_4H_7^+ in solution [PDF]

, 2003
Although numerous quantum calculations have been made over the years of the stabilities of the fluxional isomers of C4H7+, none have been reported for other than the gas phase (which is unrealistic for these ionic species) that exhibit exceptional ...

B-12(SCN)(12)(-): An Ultrastable Weakly Coordinating Dianion [PDF]

, 2017
Stable dianions that are weakly coordinating with metal ions are not common. In this work, we show that the thiocyanate SCN- anion, known for its detoxification property of cyanide CN- and antidegradation property of perovskite solar cell materials, can ...

The results of the toxicity and hazard studies of isopropyl meta-carborane with single administration to laboratory animals

Acta Biomedica Scientifica, 2018
Intensive research on the chemistry of borohydrides and the creation of high-energy fuels led to the discovery of a completely new type of organoboron compounds, which were collectively called carboranes.
