Direct evidence for a coordination-insertion mechanism of ethylene oligomerization catalysed by neutral 2,6-bisiminopyridine iron monoalkyl complexes
(Royal Society of Chemistry, 2014)
1H NMR studies on ethylene oligomerization catalysed by the neutral monoalkyl complex [Fe(Me)(iPrBIP)] allow direct observation of alkyl iron intermediates as well as reversible ethylene coordination to the metal center, ...

Sequential reduction and alkyl exchange reactions of bis(imino)pyridine dialkyliron(II) with trimethylaluminum
(American Chemical Society, 2014)
The sequence of reactions ensuing when the 2,6-bis(imino)pyridine Fe(II) dialkyl complexes [Fe(CH2SiMe3)2(BIP)] react with trimethylaluminum is described in detail. The first step is the reduction of the dialkyl to the ...

Protonolysis of Fe-C bonds of a diiminopyridineiron(II) dialkyl complex by acids of different strengths: Influence of monoanionic ligands on the spectroscopic properties of diiminopyiridine-FeY2 complexes
(Elsevier, 2014)
The reaction of the dialkyliron complex [Fe(CH2SiMe 3)2(MesBIP)] (MesBIP = 2,6-bis((N-mesityl)acetimidoyl)pyridine) with protic acids (HY) of different strengths (Y = C6F5O, CF3CO2, Cl, CF3SO3) invariably leads to the ...

Palladium(II) carboxylates and palladium(I) carbonyl carboxylate complexes as catalysts for olefin cyclopropanation with ethyl diazoacetate
(Royal Society of Chemistry (Great Britain), 2009)
Palladium(I) carbonyl carboxylate complexes [Pd(μ-CO)(μ-RCO2)]n (R = Me, n = 4; R = CMe3, n = 6) and the corresponding palladium(II) carboxylates (acetate and pivalate) catalyze the cyclopropanation of olefins with ethyl ...
