Crystal structure of 1,1'-bis[1,7-dicarba-closo-dodecaborane(11)] [PDF]

open access: yes, 2014
In the title compound, C4H22B20, the two {1,7-closo-C2B10H11} cages are linked across a centre of inversion, with C—C = 1.5401 (16) Å. The position of the second non-linking cage C atom was established unambiguously by geometric and crystallographic ...

Nido-carborane encapsulated by BODIPY zwitterionic polymers: Synthesis, photophysical properties and cell imaging

open access: yesJournal of Saudi Chemical Society, 2021
Carborane encapsulation was visualized by using fluoroboropyrrole (BODIPY) zwitterionic polymer as fluorescence marker. Firstly, a water-soluble fluorescent probe carrier was prepared by combining the BODIPY derivatives with poly (carboxybetaine ...

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.
