Abstract: Biphenol-based ligands have proven their ability to bind titanium(IV) centers and generate sophisticated self-assembled structures in which auxiliary nitrogen ligands often complete the coordination sphere of the metal and improve stability. Here, a central 4,4′-bipyridine, which acts as both a spacer and a source of monodentate nitrogen to complete the coordination sphere of the...[more]
Abstract: Gd5(L)16(H2O)8](Tf2N)15 was obtained from reaction of Gd2O3 with 1-carboxymethyl-3-ethylimidazolium chloride (LHCl). The material was found to be an ionic liquid that freezes to glassy state on cooling to −30 °C. Variable-temperature magnetic studies reveal the presence of weak magnetic intramolecular interactions in the glass. Isothermal variable-field magnetization demonstrates a...[more]
Abstract: Exploration of new organometallic systems based on polyhedral boron clusters has the potential to solve challenging chemical problems such as the stabilization of reactive intermediates and transition7 state-like species postulated for E−H (E = H, B, C, Si) bond activation reactions. We report on facile and clean B−H activation of a hydroborane by a new iridium boron cluster complex....[more]
Abstract: In this joint theoretical and experimental study, the analysis of weak interligand noncovalent interactions within Co(IV) [Cp*Co(phpy)X]+ cobaltacycles (phpy = 2-phenylenepyridine, κC,N) was carried out using the the Independent Gradient Model/Intrinsic Bond Strength Index (IGM/IBSI) method to evaluate the dependency of the catalytically desired reductive elimination pathway (RE) on...[more]
Abstract: During engine tests, it has been observed that the combined use of molybdenum dithiocarbamates (MoDTC) and methylene-bis(dithiocarbamates) (MBDTC) in formulated engine oils resulted in better fuel efficiency, keeping the friction coefficient stable at low values for a longer period of time as compared to the same oil devoid of MBDTC. Therefore, the interactions between MBDTC and MoDTC...[more]
Abstract: A copper-catalysed three-component coupling reaction between a carbonyl derivative, a terminal ynamide and an amine has been developed for the one-pot green construction of γ-amino-ynamides from simple starting materials and with a broad functional group tolerance.The copper-zeolite-catalysed three-component coupling reaction between an aldehyde or a ketone, a terminal ynamide and an...[more]
Abstract: Currently, there is a growing interest in the development of a new hierarchy of methods based on the concept of seniority, which has been introduced quite recently in quantum chemistry. Despite the enormous potential of these methods, the accurate description of both dynamical and static correlation effects within a single and in-principle-exact approach remains a challenge. In this...[more]
