Coordination Chemistry of Carborane Clusters: Metal-Boron Bonds in Carborane, Carboranyl, and Carboryne Complexes

Cesium carbonate mediated C–H functionalization of perhalogenated 12-vertex carborane anions

“…2 Ideally, WCAs function as inert charge carriers that do not undergo undesirable side reactions. Closo -Carborane 8,9 anions 2,7,10–12 are a class of WCAs, which are carbon containing analogues of polyhedral boranes. The 12-vertex carborane anions [RCB 11 X 11 1− ], and derivatives of the isoelectronic [B 12 H 12 2− ] dianion, are the most stable, 7 and they display unmatched chemical, electrochemical, 2,11,13 and thermally stability.…”

Boron rich nanotube drug carrier system is suited for boron neutron capture therapy

“…We observed that the chemical interactions that stabilize the o -carborane inside the cavity are mainly hydrophobic, mediated by the amino acid side chains of Leu and Ile of the respective cavity. Based on spatial analysis, the two center cavities each have a spherical volume of around 240 Å 3 , allowing for binding of the o -carborane clusters with their steric bulk of 148 Å 3 34 . The outer cavities have a spatial volume of around 180 Å 3 , surrounded by hydrophobic amino acid side chains which would also allow for o -carborane ligand binding.…”

Free three-dimensional carborane carbanions

“…[17][18][19] The unusual steric and electronic properties of boron cluster derivatives have been utilized in coordination chemistry, catalysis, luminescent materials, metal-organic frameworks, polymers, medicine, and energy storage. [20][21][22][23][24][25][26][27][28][29][30][31][32][33] The most commonly studied icosahedral anionic [CB 11 H 12 ] − and neutral C 2 B 10 H 12 clusters contain relatively acidic C−H bonds (for example, pK a of ortho-dicarbaborane is ca. 23).…”
