Surfactant behaviour of metallacarboranes. A study based on the electrolysis of water
(Royal Society of Chemistry, 2013-11-21)
[3,3′-Co(1,2-C2B9H11)2]−, [1]−, and its chloroderivatives have been described as displaying surfactant/aggregation properties. We have studied their behaviour as electrolytes in the water electrolysis process. The electrolysis ...
From icosahedron to a plane flattening dodecaiodo-dodecaborate by successive stripping of iodine
(Wiley, 2012-09-07)
It has been shown by electrospray ionization–ion-trap mass spectrometry that B12I122− converts to an intact B12 cluster as a result of successive stripping of single iodine radicals or ions. Herein, the structure and ...
A theta-shaped amphiphilic cobaltabisdicarbollide anion: transition from monolayer vesicles to micelles
(Wiley, 2011-05-23)
Self-assembly is ubiquitous in nature and in surfactant science.1 Globular micelles or vesicles in water are usually obtained with surfactants2 or amphiphilic block copolymers3 composed of a hydrophilic part and a hydrophobic ...
Prediction of pK(a) values of nido-carboranes by density functional theory methods
(American Chemical Society, 2006-08-25)
A great parallel exists between metal complexes of cyclopentadienyl and arene ligands on one side and metal complexes of the nido derivatives of the icosahedral o-carborane clusters. With few exceptions, the metal complexation ...
Coiled coil type neoglycoproteins presenting three lactose residues
(Elsevier, 2016-02-06)
Scaffold design, synthesis and application are relevant for biomedical research. For example, multivalent interactions, such as those between cell surface glycoproteins and lectins can influence the potency and duration ...
Lewis acid induced anomerization of se-glycosides. Application to synthesis of alpha-Se-GalCer
(American Chemical Society, 2016-01-22)
The TiCl4 induced anomerization of selenium glycosides of galacturonic acid derivatives is reported. The reaction was successful for galacturonic acid when various alkyl, alkenyl, alkynyl, saccharide, steroid, and lipid ...
Syntheses of C-substituted icosahedral dicarbaboranes bearing the 8-dioxane-cobalt bisdicarbollide moiety
(Elsevier, 2009-11-20)
The treatment of 1,2-, 1,7- and 1,12-carbaborane lithiated isomers with [3,3′-Co-8-(CH2CH2O)2-(1,2-C2B9H10)-(1′,2′-C2B9H11)] (1) at molar ratios 1:1 or 1:2 at room temperature in THF leads generally to the formation of a ...
Metallacarboranes as building blocks for polyanionic polyarmed aryl-ether materials
(American Chemical Society, 2008-09-20)
Polyanionic species have been obtained in high yield by a new route in the ring-opening reaction of cyclic oxonium [3,3′-Co(8-C4H8O2-1,2-C2B9H10)(1′,2′-C2B9H11)] (2) by using carboxylic acids, Grignard reagents, and ...
Towards the synthesis of high boron content polyanionic multicluster macromolecules
(American Chemical Society, 2009-07-31)
Reported are further consequences of the dioxane ring-opening in [3,3’-Co(8-(CH2CH2O)2-1,2-C2B9H10)(1’,2’-C2B9H11)] [1] with twelve-vertex carborane mono- and dianions. The removal of one BH vertex from the 1,2-carborane ...
Spherulization as a process for the exudation of chemical cues by the encrusting sponge C. crambe
(Nature Publishing Group, 2016-07-06)
Ecological interactions in the marine environment are now recognized to be partly held by chemical
cues produced by marine organisms. In particular, sponges are sessile animals thought to rely on
the bioactive substances ...
