Solvothermal Synthesis and Characterization of Two New Nickel Nido-Carborane Diphosphine Complexes

Journal of Cluster Science, 2011
Solvothermal synthesis method has been successfully introduced into the diphosphine carborane system, and two new nickel complexes containing nido-carborane diphosphine ligand [7,8-(PPh2)2-7,8-C2B9H10]− with the formula [Ni2(μ-Cl)(μ-OOPPh2){7,8-(PPh2)2-7,8-C2B9H10}2]·CH2Cl2 (1) and [H3O][NiBr2] {7,8-(PPh2)2-7,8-C2B9H10}·C6H6 (2) were obtained by the ...

Vibrational spectrum and structure of nido-carborane 11-CH3-2,7-C2B9H12

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1986
1. The full vibrational spectra of the nido-carborane 11-CR3-2, 7-C2B9H12 and its μ-dideutero derivative were obtained. An assignment is proposed for some of the frequencies. 2. The Raman spectrum contained broad bands belonging to the stretching vibrations of the extra-hydrogens.

17-Crown-5 ether condensed with 11-vertex nido-carborane

Russian Chemical Bulletin, 2014
The reaction of easily accessible nido-carborane [nido-7,8-(HOCH2)2-7,8-C2B9H10]- with tetraethylene glycol tosylate produces nido-carborane sodium salt condensed with 17-crown-5 ether, Na[nido-7,8-O(CH2CH2OCH2CH2OCH2)2-7,8-C2B9H10]. The structures of solvate complexes of this crown ether with acetone, ethanol, and water were studied by X-ray ...

The synthesis and biochemical evaluation of thymidine analogues substituted with nido carborane at the N-3 position

Applied Radiation and Isotopes, 2004
Several thymidine analogues substituted with closo- and nido-carborane at the N-3 position were synthesized. The nido-carboranyl thymidine analogues were designed to be effective substrates for human thymidine kinase 1 in combination with an increased water solubility sufficient for clinical application in boron neutron capture therapy.

A computational study to determine the role of σ-hole in Br/OH substituted nido-carborane and its binding capabilities

Journal of Molecular Graphics and Modelling, 2023
A detailed investigation of the σ-hole on the halogen atom present in the nido-heteroboranes is made by employing quantum mechanical methods. The bromide and the hydroxyl groups are incorporated in the exo-substituents of the nido-boranes. The potential of the bromide σ-hole was compared to that of electrostatic potential of hydroxyl group counterpart.

Synthesis of a Conjugate of Curcumin with a nido-Carborane Cluster and Its Cytotoxicity

INEOS OPEN
A conjugate of curcumin with nido-carborane was synthesized by the Cu-catalyzed 1,3-dipolar [3+2]-cycloaddition between a zwitter-ionic В-substituted nido-carborane bearing a functional azido group 9-N3(CH2)3Me2N-nido-7,8-C2B9H11 with alkynyl-tagged curcumin.

Synthesis and vesicle formation of a nido-carborane cluster lipid for boron neutron capture therapy

Chem. Commun., 2004
The nido-carborane lipid, which has a double-tailed moiety, was synthesized from heptadecanol in 5 steps. Analysis in a transmission electron microscope by negative staining with uranyl acetate showed that the lipid formed a stable vesicle in which calcein was encapsulated.

A Facile Synthesis of Nido-Carborane Polymers via Dynamic Self-Assembly by Poly(carboxybetaine methacrylate)

Journal of Nanoscience and Nanotechnology, 2021
Carborane are widely applied in boron neutron capture therapy (BNCT) field, but it is difficult to perform biocompatibility with cells due to its own water solubility differences, so how to solve the water solubility problem has always been the focus of research.

Heterodisubstituted 1,10-dicarba-closo-decaboranes from substituted nido-carborane precursors

Polyhedron, 1999
Abstract Mono- and heterodisubstituted 1,10-dicarba- closo -decaboranes 1 have been prepared from substituted nido -carboranes 3 and by carboxylation and arylation of 1-alkyl- p -carboranes. Thermal dehydrogenation followed by skeletal rearrangement of 3 furnished 1 in modest yields.
