Treatment of N,N′-bis(2,6-diisopropylphenyl)-1,4-diaza-2,3-dimethyl-1,3-butadiene with MeLi results in carbon−carbon bond formation and selective reduction of one of the imine arms to give the N-li...

Treatment of MI3 ( M = Sc, Y, Tm, and U) with three equivalents of KP3C2Bu2t in refluxing toluene led to the corresponding monomeric, formally eight coordinate, complexes [M(eta(5)-P3C2Bu2t)(2)(eta(2)-P3C2Bu2t)] in moderate yields. In the solid state

The ionicity of the metal hydride bonds of a series of iron hydrides supported by multidentate phosphine donors has been determined by means of DQCC measurements of the isotopically labelled hydrides in concentrated solution in toluene.

The aluminum-bound ferrocene complex, [Fe(η5-C5H4)2]2Al3Me5 (4), has been isolated and structurally characterized. 4 derives from metathesis between dilithiated ferrocene and AlMe2Cl. The stoichiometry of the reaction is satisfied by elimination of

Electron transmission spectroscopy is applied for the first time to a phospha-alkyne derivative, (CH 3 ) 3 CCP. Electron attachment to the π * LUMO in the gas-phase occurs at 0.63 eV. Formation of the temporary π * anion state is also observed i

Mossbauer and electron paramagnetic resonance (EPR) spectroscopic studies reveal that the iron centres in bis(imino)pyridine iron(II) olefin polymerisation pre-catalysts of the type LFeCl2 are oxidised upon treatment with methylaluminoxane (MAO) to g

The methylene-bridged Rh(I) dicarbonyl complex, [ Rh(bim) (CO) 2 + BPh 4 - ] (1) (bim = bis(N-methylimidazol-2-yl)methane), is an effective catalyst for the intramolecular hydroamination of selected ortho-alkynylanilines to give a range of benzo(dipy
