A Salt Metathesis Route To Ruthenium Carbene Complex Isomers With Pyridine Dicarboxamide-Derived Chelate Pincer Ligands

, 2007
Reaction of the doubly deprotonated pyridine 2,6-dicarboxamido ligand (1) with (PCy3)2Cl2 Ru=CHPh (3a) in THF gave a mixture of (lig)(PCy3)Ru=CHPh isomers (4).

Half‐Sandwich Nickel(II) NHC‐Picolyl Complexes as Catalysts for the Hydrosilylation of Carbonyl Compounds: Evidence for NHC‐Nickel Nanoparticles under Harsh Reaction Conditions

European Journal of Inorganic Chemistry, 2021
The cationic [NiCp(Mes-NHC-CH2py]Br complex 2 a was prepared directly by the reaction of nickelocene with 1-(2-picolyl)-3-mesityl-imidazolium bromide (1), and its PF6− derivative 2 b, by subsequent salt metathesis.

Exploring Indium Teflates: From Neutral In(OTeF5)3(THF)3 to Anionic Complexes [In(OTeF5)4(THF)2]– and [In(OTeF5)6]3–

ChemistryEurope
This study explores the synthesis and characterization of novel indium‐based pentafluoroorthotellurate (teflate) derivatives. It introduces a series of indium(III) teflate mono‐ and trianions, including [In(OTeF5)4(THF)2]– and [In(OTeF5)6]3–.

Pressure as the driving force for mechanochemical reactions on the example of ion metathesis of alkali halides upon ball milling

RSC Mechanochemistry
In situ XRD data of an ion metathesis reaction provide detailed insights into the processes occurring under ball-milling conditions. Pressure pulses exerted by the impact of milling balls drive the progress of the reaction.

Ni stabilized rock-salt structured CoO; Co1−xNixO: tuning of eg electrons to develop a novel OER catalyst

RSC Advances, 2020
The oxygen evolution reaction (OER) is a key half-reaction in hydrogen–oxygen electrolysers that is very important for efficient electrochemical energy generation, storage and fuel production that offers a clean alternative to fissile fuel combustion ...

The Parent GaH2SbH2 Monomer Stabilized by an N‐Heterocyclic Carbene

ChemistryEurope
The synthesis and characterization of the stibanyltrielanes IDipp·GaH2Sb(SiMe3)2 (1a) and IDipp·BH2Sb(SiMe3)2 (1b) are presented. 1a represents the first example for the isolation of a molecular stibanylgallane monomer stabilized only by a Lewis base (LB)

New Route to Ordered Double Perovskites: Synthesis of Rock Salt Oxides, Li4MWO6, and Their Transformation to Sr2MWO6 (M = Mg, Mn, Fe, Ni) via Metathesis

, 2005
We describe a solid-state metathesis route for the synthesis of double perovskite oxides, $Sr_2MWO_6$ $(M= Mg, Mn, Fe, Ni)$, that enabled us to obtain cation-ordered phases at a considerably lower temperature $(\sim750^oC)$ than what is employed in ...

P−P Condensation and P−N/P−P Bond Metathesis: Facile Synthesis of Cationic Tri‐ and Tetraphosphanes

Angewandte Chemie, 2019
[LC RP((PhP)2C2H4)][OTf] (4 a,b[OTf]) and [LC iPrP(PPh2)2][OTf] (5 b[OTf]) were prepared from the reaction of imidazoliumyl‐substituted dipyrazolylphosphane triflate salts [LC RP(pyr)2][OTf] (3 a,b[OTf]; a: R=Me, b=iPr; LC R=1,3‐dialkyl‐4,5 ...

Trispyrazolyl Borate Iron Thiolate Complexes and the Dependence of their O2‐Reactivity on the Reaction Space

European Journal of Inorganic Chemistry
The work presented here investigates whether the TpMesFe+ moiety, which had been previously found to mediate the dioxygenation of cysteine and cysteamine, can do the same with simple thiols, which are not functionalized by an amine group.
