Synthesis, characterization and reactivity of dyad ru-based molecules for light-driven oxidation catalysis
(Wiley, 2013-03-28)
Dyad molecules containing the 2,3,5,6-tetrakis(2-pyridyl)pyrazine (tppz) ligand with general formula [(tpy)Ru(μ-tppz)Ru(X)(L-L)]n+ (X=Cl, CF3COO, or H2O; L-L=2,2′-bipyridine (bpy) or 3,5-bis(2-pyridyl)pyrazole (Hbpp); ...
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 ...
Glycoclusters as lectin inhibitors: comparative analysis on two plant agglutinins with different folding as a step towards rules for selectivity
(Elsevier, 2015-09-23)
The emerging physiological significance of carbohydrate (glycan) protein (lectin) recognition engenders the interest to design synthetic inhibitors with a high level of selectivity among natural sugar receptors. Plant ...
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 ...
A convenient synthetic route to useful monobranched polyethoxylated halogen terminated [3,3 -Co(1,2-C2B9H11)2]- synthons
(Royal Society of Chemistry, 2009-11-15)
An atom efficient and environmentally friendly route has been developed to obtain a new range of reagents in metallacarborane chemistry having monobranched polyethoxylated cobaltabisdicarbollide synthons.
A discrete P⋅⋅⋅I I⋅⋅⋅P assembly: the large influence of weak interactions on the 31P NMR Spectra of Phosphane–Diiodine Complexes
(Wiley, 2006-02-06)
Seeing I to I: The reaction of a weakly coordinating carboranyl phosphane ligand with I2 leads to the formation of an adduct containing the bridging P⋅⋅⋅I[BOND]I⋅⋅⋅P assembly in the solid state (see picture; I purple, P ...
