Acid–base catalyses by dimeric disilicoicosatungstates and divacant γ-Keggin-type silicodecatungstate parent: Reactivity of the polyoxometalate compounds controlled by step-by-step protonation of lacunary WO sites
TL;DR: The catalytic properties of disilicoicosatungstates, [{γ-SiW10O32(H2O)2}2(μ-O)4− (2) and their parent divacant γ-Keggin type silicodecatungstate as discussed by the authors, toward C-C bond formation reactions have been investigated.
Journal ArticleDOI
Thermally stable coordinatively unsaturated alkyl complexes resistant to β-hydride elimination: TpiPrM–CH2CH3 (M = Co, Fe)
TL;DR: Coordinatively unsaturated hydrocarbyl complexes bearing β-hydrogen atoms, TpiPrM-CH2CH3 [M = Fe, Co; TPIPr = hydrotris(3,5-diisopropylpyrazolyl)borate], 14e and 15e species, respectively, are prepared; they are resistant to β-oxide elimination as mentioned in this paper.
Journal ArticleDOI
A Coordinatively Unsaturated Species with an Agostic C−H Interaction, [(κ4-TpiPr)Ru(dppe)]OSO2CF3, and Its Addition Reaction
TL;DR: In this article, the substitution reaction of the cationic aquo−ruthenium complex [TpiPrRu(dppe)(OH2)]OTf was shown to have an agostic interaction with a methyl C−H bond in the isopropyl substituent of the TpiPr ligand.
Journal ArticleDOI
N/O- and C-Bound (Enolato)palladium Complexes with Hydrotris(pyrazolyl)borato Ligands (TpR: R = iPr2, Me2) Obtained via Dehydrative Condensation between the Hydroxo Complexes TpRPd(Py)OH and Active Methylene Compounds: Factors Determining the Isomer Distribution and Dimerization of Cyano Compounds
TL;DR: In this paper, a hydroxopalladium complex bearing the TpiPr2 ligand was analyzed with active methylene compounds, X−CH2−Y 2 [dicyanomethane (2a), methyl cyanoacetate (2b), benzoylaceton...
Journal ArticleDOI
Hydrogen bonding interaction between imidazolyl N-H group and peroxide : Stabilization of Mn(III)-peroxo complex TpiPr2Mn(η2-O2)(imMeH) (imMeH = 2-methylimidazole)
