The present invention relates to an improved method of preparing metal complexes, in particular carbene-metal complexes. The method comprises the step of subjecting a salt of formula Z.sup.+—X.sup.− and a non-ionic metal salt of formula ML.sub.n or subjecting a metallate of formula Z.sup.+ . . . ML.sub.nX.sup.− to a mechanical mixing process in the presence of a base. The method allows to formation of heterocyclic carbene metal complexes such as a nitrogen-containing heterocyclic carbene (NHC)-metal complexes. The invention also relates to the use of metal complexes, in particular carbene-metal complexes such as heterocyclic carbene-metal complexes obtainable by the method according to the present invention as catalysts.

Compounds are described and characterized that bind guanine quadruplexes of DNA or RNA. Binding data and inhibition of growth data of five cancer cell lines are presented.

This method is for producing a transition metal complex represented by formula (2), the method comprising reacting a compound containing a transition metal selected from V, Cr, Mo, W, Fe, Ru, Co, Rh, Ni, Pd, and Pt with an isocyanide compound represented by formula (1) in the presence of an alkali metal supported by a solid substance which is insoluble in an organic solvent. This production method can be used to easily and efficiently produce a transition metal complex that includes a predetermined transition metal having an oxidation number of 0 and that has the same or different isocyanide compounds, without using a compound harmful to the human body. (1): (CN).sub.x—R.sup.1 {R.sup.1 represents a mono- to tri-valent organic group having 1-30 carbon atoms, and x represents an integer of 1-3}. (2): M.sup.1.sub.a(L).sub.b {M.sup.1 represents V, Cr, Mo, W, Fe, Ru, Co, Rh, Ni, Pd, or Pt, and is a zero-valent transition metal, L represents an isocyanide compound represented by formula (1), M.sup.1 and L may be the same or different from each other, “a” represents an integer of 1-8, and b represents an integer of 2-12}.

Metal complexes that exhibit multiple radiative decay mechanisms, together with methods for the preparation and use thereof.

In one aspect, phosphine compounds comprising three adamantyl moieties (PAd.sub.3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd.sub.3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.

The compound of the formula (1) and its complexes with metal cations are used for catalysis in hydroformylation processes. ##STR00001##
