Binuclear oxidative addition of Sb-Cl bonds : a facile synthetic route to main group transition element clusters and rings
Binuclear oxidative addition of Sb–Cl bonds with the clusters Os3(CO)11(NCCH3), 1, or Os3(CO)10(NCCH3)2, 2, was found to be an effective synthetic route to organometallic clusters and rings containing μ2-SbPh2 or μ3-SbPh ...
Building a lewis acidic phosphorus
Using the σ- and п-donating properties of carbodiphosphorane ligands, we recently synthesized a phosphorus (III)-containing dication. It is observed to undergo interesting reactivity with PMe3, H2O and MeOH.
Isolation of a bis(oxazol-2-ylidene)-phenylborylene adduct and its reactivity as a boron-centered nucleophile
An isolable phenylborylene species supported by two oxazol-2-ylidene ligands was synthesized and structurally characterized. Computational studies revealed the presence of lone-pair electrons on the boron atom in this ...
Synthesis of N-heterocyclic carbene stabilized catecholatoborenium cations by ligand substitution
Ligand substitution is not a common procedure for the preparation of different borenium cations. This work demonstrates that the chloride ligands of several NHC-stabilized dichloroborenium cations [NHC·BCl2][X] (NHC = ...
Dihaloborenium cations stabilized by a four-membered N-heterocyclic carbene : electron deficiency compensation by asymmetric structural changes
The synthesis, characterization and X-ray analysis of dichloro- and dibromo-borenium cations stabilized by a 4-membered carbene are reported. The ligand's structural changes, atypical for similar systems, were caused by ...
Oxidative addition of water and methanol to a dicationic trivalent phosphorus centre
Our recently synthesised phosphorus dication is observed to activate water (and methanol) under reactions conditions atypical for other systems containing a non-metal centre. This particular activation described as oxidative ...
Oxidative addition across Sb–H and Sb–Sb bonds by an osmium carbonyl cluster : trapping the intermediate
The cluster Os3(CO)11(NCCH3) oxidatively adds across the Sb–H bond in SbPh2H to afford the clusters Os3(CO)11(H)(μ-SbPh2) and Os3(CO)11(μ-H)(μ-SbPh2)Os3(CO)11. Similarly, its reaction with Sb2Ph4 afforded Os3(CO)11(μ-SbP ...
Heteroleptic Germanium(II) and Tin(II) chlorides supported by anionic ligands derived from 2,3-dimethyl-1,4-diaza-1,3-butadiene
The syntheses and structures of heteroleptic germanium(II) and tin(II) chlorides supported by anionic ligands derived from 2,3-dimethyl-1,4-diaza-1,3-butadiene are described. The reaction of ArN=C(Me)C(Me)=NAr (L, Ar = ...
Activation of a 1-chlorophosphirane complex by aluminum trichloride : generation and trapping of [Fc-P-W(CO)5] (Fc = Ferrocenyl)
Aluminum trichloride catalyzes the ring opening of a 1-chlorophosphirane W(CO)5 complex and its reaction with thiophene and ferrocene to give the corresponding 1-(2-thienyl)- and 1-ferrocenylphosphirane derivatives. The ...
Isolation of an imino-N-heterocyclic carbene/germanium(0) adduct : a mesoionic germylene equivalent
An autoionization of germanium dichloride/dioxane complex with an imino-N-heterocyclic carbene ligand (L) afforded a novel germyliumylidene ion, [(L)GeCl]+[GeCl3]−, which was fully characterized. Reduction of the ...
