Photoinduced Selective B–H Activation of nido-Carboranes [PDF]

Journal of the American Chemical Society
The development of new synthetic methods for B-H bond activation has been an important research area in boron cluster chemistry, which may provide opportunities to broaden the application scope of boron clusters. Herein, we present a new reaction strategy for the direct site-selective B-H functionalization of nido-carboranes initiated by photoinduced ...

The Far Side of Carboranes: Anticancer Active Monocations and Ambiently Stable Dications. [PDF]

Angew Chem Int Ed Engl
This work describes the synthesis of bench‐stable dicationic carboranes. Their enhanced electrophilicity is documented by opening the clusters with weak nucleophiles or dihydrogen. The surprising stability of positively charged carboranes in water enabled a study of their in vitro antiproliferative activity, which surpassed the effects of doxorubicin ...

Site-Selective B─H Activation via HAT Toward Xanthyl-closo-Carboranes as Bench-Stable Precursors of Organosulfur Boron Clusters. [PDF]

Angew Chem Int Ed Engl
A light mediated direct regioselective B─H functionalization, via hydrogen atom transfer (HAT), is described. Unexplored xanthyl‐closo‐carboranes as novel bench‐stable and versatile platforms to access sulfur‐containing boron clusters are reported for the first time.

A Redox-Tunable Carborane Crown: Toward Highly Selective Electrochemical Lithium Capture. [PDF]

Chemistry
Electrochemical reduction transforms a new carborane–crown into a potent 2e− reduced nido anion with a redox‐tunable cavity that captures Li⁺ selectively over Na⁺ and K⁺. The coupling of electronic control and size‐matched binding offers a blueprint for selective, rapid lithium recovery for next‐generation direct lithium extraction. Abstract Lithium is

Carboranes as unique pharmacophores in antitumor medicinal chemistry

Molecular Therapy: Oncolytics, 2022
Carborane is a carbon-boron molecular cluster that can be viewed as a 3D analog of benzene. It features special physical and chemical properties, and thus has the potential to serve as a new type of pharmacophore for drug design and discovery.

Crystal Structure of 9-Dibenzylsulfide-7,8-dicarba-nido-undecaborane 9-Bn₂S-7,8-C₂B₉H₁₁

Molbank, 2021
The crystal structure of 9-dibenzylsulfide-7,8-dicarba-nido-undecaborane 9-Bn2S-7,8-C2B9H11 was determined by a single-crystal X-ray diffraction. One of the benzyl groups is located above the open face of the carborane cage with a short H···H distance (2.

Water-soluble BODIPY-nido-carborane nanoparticles applied to biocompatibility tumor cell imaging [PDF]

Photochemical & Photobiological Sciences, 2022
In this article, o-carborane has a high boron content, high hydrophobicity, and good chemical stability. It has been widely used in the fields of biology and medicine, especially in the application of boron neutron capture therapy (BNCT). However, o-carborane is a fat-soluble compound, its hydrophobicity is too strong, and its bioavailability is poor ...
