Unusual cage rearrangements in 10-vertex nido-5,6-dicarbaborane derivatives : An interplay between theory and experiment [PDF]

open access: yes, 2016
The reaction between selected X-nido-5,6-C2B8H11 compounds (where X = Cl, Br, I) and "Proton Sponge" [PS; 1,8-bis(dimethylamino)naphthalene], followed by acidification, results in extensive rearrangement of all cage vertices.

Carborane-Based Analog of Rev-5901 Attenuates Growth of Colon Carcinoma In Vivo

open access: yesMolecules, 2022
Lipoxygenases convert polyunsaturated fatty acids into biologically active metabolites such as inflammatory mediators—prostaglandins and leukotrienes. The inhibition of lipoxygenases is increasingly employed in the treatment of cancer.

Site‐Selective B─H Activation via HAT Toward Xanthyl‐closo‐Carboranes as Bench‐Stable Precursors of Organosulfur Boron Clusters

open access: yesAngewandte Chemie, EarlyView.
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.

The effects of halogen elements on the opening of an icosahedral B12 framework [PDF]

open access: yes, 2017
The fully halogenated or hydrogenated B12X12 (X = H, F, Cl, Br and I) clusters are confirmed to be icosahedral. On the other hand, the bare B12 cluster is shown to have a planar structure. A previous study showed that a transformation from an icosahedron

Reactions of Experimentally Known Closo-C2B8H10 with Bases. A Computational Study

open access: yesCrystals, 2020
On the basis of the direct transformations of closo-1,2-C2B8H10 with OH(−) and NH3 to arachno-1,6,9-OC2B8H13(−) and arachno-1,6,9-NC2B8H13, respectively, which were experimentally observed, the DFT computational protocol was used to examine the ...
