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 ...

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.

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

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.

A Strong Lewis Acidic Diethylsilylium Catalyst for Direct Sulfonamidation of Challenging Ketones

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Low‐substitution‐order silylium ions (R2HSi+) exhibit exceptional Lewis acidic activity. We report diethylsilylium‐catalyzed reductive sulfonamidation of functionalized ketones to access β‐amino esters. The in situ generated ion pair shows enhanced reactivity, with diethylsilane serving as both reductant and precatalyst. The developed protocol proceeds

Stirred, Not Stacked: Co‐Evaporated C60:BCP Electron Transport Layers for Efficient and Robust Metal‐Halide Perovskite Solar Cells

Advanced Electronic Materials, Volume 12, Issue 15, 10 August 2026.
Electron transport layers using sequential C60|BCP stacks in perovskite solar cells suffer from parasitic absorption and interfacial limitations. We demonstrate that co‐evaporated C60:BCP layers reduce sub‐600 nm absorption while maintaining charge extraction, improving interfacial quality, reducing non‐radiative losses, and achieving efficiencies up ...
