Catalytic asymmetric allylic alkylation employing heteroatom nucleophiles: a powerful method for C-X bond formationA new cage isomer of C 70 , Sc 2 S@C 2 (7892)-C 70 , has been isolated and characterized by mass spectrometry, UV-Vis-NIR absorption spectroscopy, cyclic voltammetry and DFT calculations. The combined experimental and computational studies lead to the unambiguous assignment of the cage symmetry to C 2 (7892)-C 70 . The comparison between Sc 2 S@C 2 (7892)-C 70 and related endohedral 10 structures has been discussed. A close structural resemblance between Sc 2 S@C 2 (7892)-C 70 and Sc 2 S@C s (10528)-C 72 suggests that the conversion of these two molecules may be the result of a simple insertion of C 2 and the structural difference between Sc 2 S@C 2 (7892)-C 70 and Sc 3 N@C 2v (7854)-C 70 shows that the nature and geometry of the encaged cluster plays an important role on the selection of the non-IPR cage.
Previous studies performed on samples of MoOF4 dissolved in anhydrous hydrogen fluoride (aHF) solutions have indicated the presence of the [Mo2O2F9]– anion. Building upon this earlier work, MoOF4, and MF (M = Li–Cs) were dissolved in aHF solutions to produce M[Mo2O2F9] (M = Li–Cs) salts. Structural analysis of the obtained compounds was performed using single‐crystal X‐ray diffraction. This study provides the first single crystal structures for the [MoVI2O2F9]– anion. Additionally, IR and Raman spectroscopy were used to characterize each salt. These spectra were compared to calculated ones for the solid‐state structure of each salt using the DFT‐PBE0 density functional method. The calculated spectra were used to give band assignments in the experimentally obtained spectra.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
