Synthesis of phosphanaphthalenes and nido-carborane fused six-membered phosphacycles

Chinese Chemical Letters, 2021
Abstract A simple method to synthesize luminescent λ5-phosphanaphthalenes and zwitterionic nido-carborane fused six-membered phosphacycles was developed from the reaction of ortho-phosphinobenzoaldehydes or ortho-phosphinocarboranylaldehydes with an electron-deficient alkyne, respectively. Similar results were obtained with the imino analogues.

On the reaction of nido-carborane with thiourea

Russian Chemical Bulletin, 2016
A reaction of the protonated form of 7,8-dicarba-nido-undecaborate anion 7,8-C2B9H13 with thiourea leads to the formation of a mixture of 9- and 10-thiuronium derivatives, the alkaline hydrolysis of which gives a mixture of the corresponding mercapto derivatives of nido-carborane.

Synthesis and characterization of nido-carborane-cobalamin conjugates

Nuclear Medicine and Biology, 2000
Three vitamin B12 (cyanocobalamin) conjugates bearing one nido-carborane molecule or two nido-carborane molecules linked to the propionamide side chains via a four carbon linker have been synthesized. Reaction of o-carboranoylchloride with 1,4-diaminobutane in pyridine produced nido-carboranoyl(4-amidobutyl)amine, which was linked to the b- and d ...

Negative ion mass spectra of nido carboranes

Journal of the American Chemical Society, 1972
Abstract : The negative ion mass spectra of 2,3-dicarbahexaborane(8), 2-methyl-nido-2,3-dicarbahexaborane(8) and 2,3-dimethylnido-2,3-dicarbahexaborane(8) have been investigated. Evidence has been found to show that formation of negative ions in these nido carboranes predominately via resonance capture and dissociative resonance capture mechanisms ...

Tungsten carbonyl σ-complexes of nido-carborane thioethers

Journal of Organometallic Chemistry, 2012
Abstract Nido-carborane thioethers Cs[X-(CH2)nSMe-7,8-C2B9H11)] (X = 7, 9, n = 0; X = 9, n = 1) were synthesized and their reactions with tungsten carbonyl W(CO)5(THF) were investigated. The corresponding pentacarbonyl tungsten complexes were isolated as cesium salts and characterized.

X-Ray crystal and molecular structure of the nido-carborane B7C2H7Me2

Journal of the Chemical Society, Chemical Communications, 1972
The nido-carborane B7C2H7Me2 occurs as a bicapped Archimedean antiprism with the 6 position missing, methylated carbon atoms in the 1 and 2 cage positions, and bridging hydrogen atoms between the 7–10 and 9–10 positions.

Synthesis of new nido-carborane based carboxylic acids and amines

Polyhedron, 2018
Abstract A series of new nido-carborane based carboxylic acids 10-HOOC(CH2)n(Me)S-7,8-C2B9H11 (n = 1–4) was prepared by alkylation of tetrabutylammonium salt of 10-methylthio-7,8-dicarba-nido-caborane with ω-halogenoalkyl esters or nitriles followed by acid hydrolysis. Likewise nido-carborane based amines 10-H2N(CH2)n(Me)S-7,8-C2B9H11 (n = 2, 3) were

An ab initio/IGLO/NMR study of the nido-carborane C2B6H10

Inorganic Chemistry, 1992
The structure of the eight-vertex nido-carborane C 2 B 6 H 10 has been investigated by employing the ab initio/IGLO/NMR method. The experimental 11 B NMR chemical shifts for C 2 B 6 H 10 are compatible with three different structures (one static and two requiring fluxionality).
