Ab Initio/GIAO-CCSD(T) investigation of 11B–13C NMR chemical shift relationships in trifluoro- and trihydridoborate anions and their isoelectronic neutral alkane derivatives

Computational NMR of charged systems

This review covers NMR computational aspects of charged systems-carbocations, heterocations, and heteroanions, which were extensively studied in a number of laboratories worldwide, first of all, at the Loker Hydrocarbon Research Institute in California directed for several decades by a distinguished scientist, the Nobel laureate George Andrew Olah. The first part of the review briefly outlines computational background of the modern theoretical methods applied to the calculation of chemical shifts and spin-spin coupling constants at the DFT and the non-empirical levels. The second part of the review deals with the historical results, advances, and perspectives of the computational NMR of classical carbocations like methyl cation, CH₃⁺ , and protonated methane, CH₅⁺ , together with their numerous homologs and derivatives. The third and the forth parts of this survey are focused on the NMR computational aspects of accordingly, heterocations and heteroanions, the organic and inorganic ions with a charge localized mainly on heteroatoms like boron, oxygen, nitrogen, and heavier elements.

The pentafluoroethyltrihydridoborate anion: from shock sensitive salts to stable room temperature ionic liquids

Salts of the first monoperfluoroalkylhydridoborate anion [C₂F₅BH₃]⁻, which is weakly hydridic, range from explosive metal salts to stable ionic liquids.
