Metallacarboranes and their interactions: theoretical insights and their applicability
(Royal Society of Chemistry, 2012-02-14)
This tutorial review will deal with the study of metallacarboranes and their interactions with other molecules from a theoretical point of view. This contribution is devoted to guide experimental chemists through calculations ...
Controlling the pirouetting motion in rotaxanes by counterion exchange
(American Chemical Society, 2014-07-25)
A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide ...
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 ...
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 ...
Unprecedented B―H activation through Pd catalysed B―Cvinyl bond coupling on borane systems
(Wiley, 2011-04-20)
A Pd-induced cascade B–Cvinyl coupling that produces multiple B–Cvinyl bonds starting from a single B–I bond has been demonstrated. The process is most probably stimulated by the geometrical disposition of the B–H bonds ...
Relaxed but highly compact diansa metallacyclophanes
(American Chemical Society, 2011-09-09)
A series of monoansa [μ-1,1′-PR-3,3′-Co(1,2-C2B9H10)2]− and diansa [8,8′-μ-(1″,2″-benzene)-μ-1,1′-PR-3,3′-Co(1,2-C2B9H9)2]− (R = Ph, tBu) cobaltabisdicarbollidephanes have been synthesized, characterized and studied by ...
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 ...
Additive tuning redox potential in metallacarboranes by sequencial halogen substitution
(Wiley, 2010-04-21)
The first artificially made set of electron acceptors is presented that are derived from a unique platform Cs[3,3′-Co(C2B9H11)2], for which the redox potential of each differs from its predecessor by a fixed amount. The ...
Widely applicable metallacarborane reagents for π-conjugated systems
(American Chemical Society, 2014-05-12)
The compounds [N(CH3)4][3,3′-Co(8-(p-C6H4C2H3)-1,2-C2B9H10)(1′,2′-C2B9H11)], [N(CH3)4][3,3′-Co(8-(p-C6H4CHO)-1,2-C2B9H10)(1′,2′-C2B9H11)], and [N(CH3)4][3,3′-Co(8-(m-C6H4CHO)-1,2-C2B9H10)(1′,2′-C2B9H11)] were synthesized ...
