p-Fluorophenylisocyanide (CNPhpF) reacts with [Re(CO)5Br] under stepwise exchange of the carbonyl ligands depending on conditions applied. The reaction stops formation fac-[Re(CO)3Br(CNPhpF)2] in boiling THF. An ongoing is observed at higher temperatures, e. g. refluxing toluene, final [Re(CNPhpF)6]+ cation. progress reactions has been studied by 19F NMR spectroscopy and structures [Re(CO)Br(CN...
We have characterized the covalent binding of the CO(2) reduction electrocatalyst ReC0A (Re(CO)(3)Cl(dcbpy) (dcbpy =4,4'-dicarboxy-2,2'-bipyridine)) to the TiO(2) rutile (001) surface. The analysis based on sum frequency generation (SFG) spectroscopy and density functional theory (DFT) calculations indicates that ReC0A binds to TiO(2) through the carboxylate groups in bidentate or tridentate li...

Recent $\ensuremath{\mu}\mathrm{SR}$ measurements revealed remarkable signatures of spontaneous magnetism coexisting with superconductivity in elemental rhenium. Thus, pure rhenium could be the first crystal where unconventional is realized nature. Here we provide a quantitative theory that uncovers nature superconducting instability by incorporating every details electronic structure together ...
We report a variety of rhenium complexes supported by bidentate and tridentate phosphinoamine ligands their use in the formation advanced biofuel isobutanol from methanol ethanol. Rhenium pincer 1–3 are effective catalysts for this process, with 2 giving 35% yields, 97% selectivity liquid fraction, over 16 h catalyst loadings as low 0.07 mol %. However, these show poorer overall selectivity, si...
Based on the study of current-voltage dependences during co-deposition nt electrical reduction rhenium and molybdenum from sulfuric acid a Pt electrode, conditions for deposition alloy nanocoatings Re-Mo system were established. The influence various factors, such as content components in electrolyte, current density, temperature, acidity solutions, etc., composition quality coatings was studie...
