Organic lithium salts suitable for use in electrolytes for primary or secondary rechargeable batteries include de-localized bulky anions over Lewis acid fragments, typically BF3, and organic moieties. The organic moieties may be, for example, anions derived from fused nitrogen heterocycles (e.g. benze...
The addition reaction between BF3, BH3, and NH3 are studied by the SCFMO method including all valence electrons. It is concluded that no primary reorganisation of the acceptor is necessary and the energy due to formation of the donor acceptor bond at all distances offsets both the reorganisatio...
Lewis acidfree base porphineUsing various theoretical methods, the complexation of BF 3 as a Lewis acid with free base porphine has been investigated. It has been shown that addition of a BF 3 molecule to porphine in the first step produces a stable 1:1 complex, and addition of a second ...
Ab initio quantum chemical calculations, literature thermochemical studies in both gas and condensed phases, and simple chemical rules and regularities are used to show that SO 3 is a stronger Lewis acid than BF 3 . We show that this is due to the composite effect of relative bond strengths ...
Lewis acid gases, PF5, BF3 and SiF4 are liberated from their ammonium, alkali metal and pyridinium fluorocomplexes, NH4PF6, NaPF6, KPF6, C5H5NHPF6, C5H5NHBF4 and (C5H5NH)2SiF6, when treated with sulphur trioxide at room temperature. The dissociated ammonium/alkali metal fluorides as well...
In this work, the nature of MH···B/Al interaction between Cp2M(L)H(M=V, Nb, and Ta) and BF3/AlF3 in 1:1 Lewis acid–base adducts as well as the influences of different types of ligands on the interactions is investigated. The results show that in Cp2M(L)H···BF3/AlF3, ...
