    The Lewis-acid behavior of [SF3][MF6] (M = Sb, As) salts toward mono- and bidentate nitrogen bases was explored. Reactions of [SF3][MF6] with excesses of CH3CN and C5H5N yielded [SF3(L)2]+ (L = CH3CN, C5H5N) salts, whereas ...

    The enhanced reactivity of [WF5]+ over WF6 has been exploited to access a neutral derivative of elusive WF5. The reaction of WF6(NC5H5)2 with [(CH3)3Si(NC5H5)][O3SCF3] in CH2Cl2 results in quantitative formation of ...

    Transition-metal hexafluorides do not exhibit fluoride-ion donor properties in the absence of donor ligands. We report the first synthesis of donor-stabilized [MF5]+ derived from a transition-metal hexafluoride via ...

    The reactions of WF6 with pyridine, 4-methylpyridine, 4-(dimethylamino)pyridine, and 4,4′-bipyridine (4,4′-bipy) in CH2Cl2 afford the Lewis-acid-base adducts WF6(4-NC5H4R) (R = H, CH3, N(CH3)2) and F6W(4,4′-bipy)WF6 as ...

    Lewis acid-base adducts between AsF5 and the ketones, acetone, cyclopentanone, and adamantanone, were synthesized from SO2 and CH2Cl2 solutions. These adducts, which contain O---As pnictogen bonding interactions, were found ...

    Lewis acid–base adducts between SF4 and the oxygen bases tetrahydrofuran, cyclopentanone, and 1,2-dimethoxyethane were synthesized and characterized by Raman spectroscopy and X-ray crystallography. Crystal structures of ...

    Amorphous [W(NC6F5)F4]x has been synthesized by the reaction of [C5H5NH][W(NC6F5)F5] with AsF5 in CH2Cl2. The reaction of [W(NC6F5)F4]x with CH3CN yields monomeric W(NC6F5)F4(NCCH3), whereas reaction with a sub-2-fold ...

    Investigation of a triamidoamine-supported zirconium hydride intermediate, important to a range of catalytic reactions, revealed the potential Lewis acidity of [k5-N,N,N,N,C-(Me3SiNCH2CH2)2NCH2CH2NSiMe2CH2]Zr (1). A ...
