This article provides an overview of the rich chemistry rhenium and manganese decacarbonyls, M2(CO)10 (M = Re, Mn) their acetonitrile derivatives [M2(CO)8(NCMe)2] as precursors for synthesis new di‒, tri‒ tetranuclear complexes derived from a wide range heterocyclic thiols such pyridine-2-thiol, pyrimidine-2-thiol, tetrahydropyrimidine-2-thiol, 2-mercapto-1-methylimidazole, benzimidazole-2-thio...

Compounds composed of [Cu(HIm, metIm)2–3L] ∙ nH2O (n = 0, 2) were obtained during the interaction slightly soluble tartrate and copper(II) salicylate CuL 1–2, L2−—Tar2−, Sal2−) with imidazole (HIm) 2-methylimidazole (metIm). Mono- bi-ligand salts analyzed; process their thermal decomposition was studied. The solubility constants KS CuC4H4O6 2H2O CuC7H4O3 H2O at ionic strength 0.3 determined. IR...

A new high-performance liquid chromatography (HPLC) stationary phase was firstly synthesized based on the ionic liquid 2-ethyl-4-methylimidazole chloride. And the performances of the resulting stationary phase were determined by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), and (13)C nuclear magnetic resonance (NMR) spectroscopy. The retention characteristics of the resu...

A series of DNA double helices containing different numbers of silver(I)-mediated base pairs involving the artificial nucleobases imidazole or 2-methylimidazole has been applied for the generation of DNA-templated silver nanoclusters. The original Ag(I)-containing nucleic acids as well as the resulting nanoclusters and nanoparticles have been characterized by means of UV/Vis spectroscopy, circu...

The acceleration, by a factor of 2500, of the hydrolysis of endo-5-[4'(5')imidazolyl]bicyclo[2.2.1]hept-endo- 2-yl trans-cinnamate by 0.5 M sodium benzoate in 42 mol% dioxane in water can be explained without resort to operation of a "charge-relay" mechanism similar to that often postulated to account for the enzymatic activity of serine proteases. The degree of ionization of 4-methylimidazole ...

The stable phosphonate derivatives have easily synthesized by the reactions involving trialkyl(aryl) phosphites and dimethyl acetylenedicarboxylate in the presence of 4-nitrophenol and/or acid chlorides, dialkyl(aryl) phosphites and N-methylimidazole at 70 oC under solventfree conditions.

Six new mononuclear [FeIII(LBr,Cl)X]-complexes (LBr,Cl is the dianionic penta-N3O2-dentate Schiff base ligand N,N?-bis(2’-hydroxy-3-bromo-5-chlorobenzylidene)-1,6-diamino-3-azahexane; X: Cl?, N3?, NCO?, NCS?, NCSe?, CN?) were synthesized and their structures, magnetic electrochemical properties studied. Structure analysis measurements showed that [FeIII(LBr,Cl)CN] in low spin state other five c...
