Additive tuning redox potential in metallacarboranes by sequencial halogen substitution
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 discrete P⋅⋅⋅I I⋅⋅⋅P assembly: the large influence of weak interactions on the 31P NMR Spectra of Phosphane–Diiodine Complexes
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 ...
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.
Chemical, electrochemical and photochemical catalytic oxidation of water to dioxygen with mononuclear ru complexes
Four new RuII[BOND]Cl and RuII[BOND]H2O complexes containing the meridional 2,2’:6’,2”-terpyridine (trpy) ligand and the chelating 2-(5-phenyl-1H-pyrazol-3-yl)pyridine (H3p) ligand of general formula in- and out-[RuII(tr ...
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 ...
Unprecedented B―H activation through Pd catalysed B―Cvinyl bond coupling on borane systems
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 ...
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 ...
Light driven styrene epoxidation and hydrogen generation using H2O as an oxygen source in a photoelectrosynthesis cell
(Royal Society of Chemistry, 2015-10-02)
A dye-sensitized photoelectrosynthesis cell (DSPEC) has been prepared for the oxidation of alkenes to epoxides and evolution of hydrogen using water as an oxygen source and sunlight. A Ru oxidation catalyst, 2,2+ , is ...
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 ...
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]−, −, 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 ...
