This paper presents the results of studies anti-seize properties (2,2-dimethyl-4-methylene1,3-dioxolane-allyl and benzyl)disulfides synthesized on basis 2,2-dimethyl-4-chloromethyl-1,3- dioxolane, sodium disulfide allyl benzyl chlorides, respectively, in composition transmission oils. The compounds are new not previously described literature, structure which has been proven by studying their ph...

By utilizing different coordination properties of a lanthanide ion and a transition metal ion, a heterometallo-supramolecular polymer with Eu(III) and Fe(II) ions introduced alternately (polyEuFe) was precisely prepared via stepwise complexation of the metal ions to a new unsymmetrical ligand with both a dicarboxylate-substituted terpyridine and an unsubstituted terpyridine. The polymer showed ...

The title compound, [Cu(C(14)H(13)N(2)O(2))(N(3))], is a monomeric neutral complex with one unsymmetrical 6-meth-oxy-2-(2-pyridylmethyl-imino-meth-yl)phenolate Schiff base ligand and one azide ligand. The mol-ecules are connected by a combination of two π-π inter-actions [centroid-centroid distances 3.359 (3) and 3.378 (2) Å] and one C-H⋯N hydrogen bond into a two-dimensional supra-molecular ne...

The first example of a direct aldehyde–ketone coupling using the secondary amine piperidine as base in the presence of MgI2 to generate high selectivity of anti-aldol products from unmodified ethyl ketones in high yield is reported. The coupling reactions were carried out in a one-pot reaction by mixing four reaction components at room temperature. In the case of unsymmetrical ketones, addition...

Activated enol ethers derived from esters or the dinitrile of malonic acid, or from pentane-2,4-dione were treated with hydrazine hydrate. The structures of the obtained products - pyrazoles 5 - were studied with a focus on tautomerism and supramolecular structure. A reverse addition of the reagents led to the isolation of two novel products, namely bis-enehydrazines 6 with an unsymmetrical arr...
