Carborane Guests for Cucurbit[7]uril Facilitate Strong Binding and on Demand Removal [PDF]

, 2020
High affinity guest have been reported for the macrocyclic host cucurbit[7]uril (CB[7]), enabling widespread applications, but preventing CB[7] materials from being returned to their guest-free state for reuse.

Trigonal Phosphine Umpolung: Electrophilicity Driven by a Redox‐Active Boron Cluster

Chemistry – A European Journal, EarlyView.
Coupling of a phosphine to a redox‐active cluster enables polarity reversal, or umpolung, at phosphorus. Phosphines are classically known for their nucleophilicity, and while electrophilic reactivity has been observed in geometrically constrained, non‐trigonal systems, similar behavior in ordinary trigonal phosphines is rare.

Two New closo- or nido-Carborane Diphosphine Complexes: Synthesis, Characterization and Crystal Structures [PDF]

Bulletin of the Korean Chemical Society, 2011
Two new carborane complexes containing closo- or nido-carborane diphosphine ligands with the formula: complex (1) and (2) have been synthesized and characterized by elemental analysis, 1H and 13C NMR spectroscopy and X-ray structure determination. The X-ray structure analyses revealed that the carborane diphosphine ligand was degraded from closo-1,2 ...

Organocatalytic B–H Functionalization of Carboranes via Photo‐Induced Hydrogen Atom Transfer

ChemistryEurope, Volume 4, Issue 7, July 2026.
Visible‐light organocatalytic hydrogen atom transfer enables direct carborane B─H bond functionalization. A photocatalytically generated cationic aminium radical selectively abstracts hydrogen from hydridic boron sites, forming boron‐centered radicals that couple with activated olefins or imines to deliver B‐functionalized carboranes under mild ...

Palladium-Catalyzed Heck Reactions of Styrene Derivatives and 2-Iodo-p-carborane [PDF]

, 2016
p-Carborane has been vinylated on the 2-B-atom in high yields using the Heck reaction. Thus, the reaction between 2-iodo-p-carborane and various styrenes [4-H-, 4-C6H4-, 4-Cl-, 4-Br-, 4-NO2-, 4-CH3O-, and 4-CH3-] resulted in the production of the ...
