Multinuclear aluminum cocatalysts have been obtained by the reaction of various phenols, alcohols or diols with trimethylaluminum and were used in situ or as isolated, well-defined species, for the activation of an iron(ii) or an iron(iii) pre-catalyst for the oligomerization of ethylene. The best cocatalyst candidate involves 2,2'-biphenol () in a /AlMe3 ratio of 2/3.

The previously synthesized strained distannadiyl-ansa half-sandwich complex [{κ-SntBu2SntBu2-(η-C5H5)}Ru(CO)2] was investigated with respect to its reactivity toward group 16 elements and bis(tert-butylisonitrile)palladium(0). All products were analyzed by multinuclear NMR spectroscopy, IR spectroscopy and elemental analysis. [{κ-SntBu2SSntBu2-(η-C5H5)}Ru(CO)2] was furthermore characterized by ...

A dual-templated approach for the controllable synthesis of metal cluster complexes is described. By using an acetylide-containing anion with specific geometry as a central template and a macrocyclic coordinative compound as a peripheral one, two multinuclear silver-acetylide cluster-encapsulated supramolecular boxes were synthesized.

Treatment of a newly prepared digold(i) complex, [Au2(dppe)(H2msa)2] ([H41]; dppe = 1,2-bis(diphenylphosphino)ethane, msa = thiomalate), with Ni(2+) gave two interconvertible multinuclear complexes, [Ni{Au2(dppe)(msa)2}](2-) ([2](2-)) and [Ni3{Au2(dppe)(Hmsa)2}{Au2(dppe)(msa)2}(MeOH)3] ([3]), dependent on solution acidities.

Homoleptic coordination of the neutral diphosphines Me2P(CH2)2PMe2 and o-C6H4(PMe2)2 to the hard Li(+) and Na(+) cations is achieved using Li[Al{OC(CF3)3}4] and Na[B{3,5-(CF3)2-C6H3}4] as 'naked' cation sources. Crystallographic, solid state and solution multinuclear NMR studies confirm distorted octahedral coordination solely via three chelating diphosphines in these unique species.
