Reactivity of polynuclear zinc-thiolate sites

The proton affinities of a series of monoand polynuclear zinc-thiolate compounds, mimicking zing finger protein and metallothioneins sites, have been investigated by Density Functional Theory calculations. This allows to evaluate the intrinsic nucleophilicity of synthetic and natural zinc-bound thiolates and to compare their relative reactivities. The site specificity of the experimental thiola...

Thiolate ligands in metallothionein confer redox activity on zinc clusters.

We postulate a novel and general mechanism in which the redox-active sulfur donor group of cyst(e)ine confers oxidoreductive characteristics on stable zinc sites in proteins. Thus, the present, an earlier, and accompanying manuscripts [Maret, W., Larsen, K. S. & Vallee, B. L. (1997) Proc. Natl. Acad. Sci. USA 94, 2233-2237; Jiang, L.-J., Maret, W. & Vallee, B. L.

Covalent palladium-zinc bonds and their reactivity.

Photolysis of ((F)PNP)Pd-Et in the presence of Et(2)Zn leads to the formation of ((F)PNP)Pd-Zn-Pd(PNP(F)), the first example of a compound with a covalent Pd-Zn bond.

A 1D Schiff base zinc polymer as a versatile metallo-ligand for the synthesis of polynuclear zinc cages.

The 1D polymeric Schiff base zinc complex, [LZn(2)Et(2)](n), where LH(2) = (NN'-ethylene-bis(4-iminopentan-2-one)) has been demonstrated as a useful synthetic metallo building block for the synthesis of homo and heteronuclear zinc cages. The reaction of [LZn(2)Et(2)](n) with CdI(2) afforded the hetero-nuclear cage, 1, [L(2)Zn(4)(Et)(2)CdI(4)], while reaction with HgI(2) afforded a hexanuclear z...
