The reaction of the Cu halides (II) with the peptide ligands (I) which resemble part of the metal‐chelating portion of the antitumor drug bleomycin affords the new title complexes (III) and (IV).

(δ = 1.5), prepared by solid‐state reaction of Y2O3, BaO, and CuO at 910 °C, has been measured from 5.3 to 345 K by adiabatic calorimetry.

As part of the systematic synthetic approach to metallobleomycins, a ligand (I) was synthesized recently, which mimics a major part of the metal‐chelating locus of the antitumor drug.

Treatment of the Ru4 cluster (I) with two equiv. Cu salt (II) or (Ag(NCMe)4)PF6, followed by the addition of two equiv. of the phosphane (III) affords the novel mixed‐metal clusters (IV) (space group P1, Z=2) and (V), respectively.

The compounds (I) catalyze the oligomerization and isomerization of n‐butenes at room temp. under autogeneous pressure.

The peptides (III) and (VII), which are synthesized in high yield via the ester route, can coordinate through three N centers, an aromatic N, a peptide N and an imidazolyl N, and thus resemble part of the metal‐chelating region of bleomycin.

The conditions for the deposition of the first layer single‐phase CuInSe2are studied using spray solutions containing InCl3, CuCl2, and N,N‐dimethylselenourea.

Attempts to synthesize the Co(III) complex of the compound (I), a designed ligand that mimics a major portion of the metal‐chelating locus of the antitumor drug Bleomycin, afford the two novel imidazolate‐bridged trimeric and tetrameric complexes (IIIa) (space group R3, Z=12) and (IIIb) (P4/n, Z=2).

Treatment of the vinyldioxolanes (I) and (III) with Lewis acids results in ring‐enlargement, forming the oxocycloheptatetrahydrofurans (II) and (IV).

Studies on the synthetic analogues of metallobleomycins reported so far are all restricted to measurements in solutions.

Syntheses of novel polymethylene‐bridged derivatives (VI), (VII), (IX) of adenine are performed.

The hydrogendifluorides (I) are prepared by a simple reaction of their corresponding bromides or iodides with an ion‐exchange resin containing HF2‐.
