  abstract  = {Salts of the tetrakis(pentafluoroethyl)aluminate anion [Al(C\(_{2}\)F\(_{5}\))\(_{2}\)]\(^{-}\) were obtained from AlCl\(_{3}\) and LiC\(_{2}\)F\(_{5}\). They were isolated with different counter-cations and characterized by NMR and vibrational spectroscopy and mass spectrometry. Degradation of the [Al(C\(_{2}\)F\(_{5}\))\(_{4}\)]\(^{-}\) ion was found to proceed via 1,2-fluorine shifts and stepwise loss of CF(CF\(_{3}\)) under formation of [(C\(_{2}\)F\(_{5}\))\(_{4-n}\)AlF\(_{n}\)]- (n=1-4) as assessed by NMR spectroscopy and mass spectrometry and supported by results of DFT calculations. In addition, the [(C\(_{2}\)F\(_{5}\))AlF\(_{3}\)]\(^{-}\) ion was structurally characterized.},

  abstract  = {Different types of high-yield, easily scalable syntheses for cyano(fluoro)borates Kt[BF\(_{n}\)(CN)\(_{4-n}\)] (n=0-2) (Kt=cation), which are versatile building blocks for materials applications and chemical synthesis, have been developed. Tetrafluoroborates react with trimethylsilyl cyanide in the presence of metal-free Br{\o}nsted or Lewis acid catalysts under unprecedentedly mild conditions to give tricyanofluoroborates or tetracyanoborates. Analogously, pentafluoroethyltrifluoroborates are converted into pentafluoroethyltricyanoborates. Boron trifluoride etherate, alkali metal salts, and trimethylsilyl cyanide selectively yield dicyanodifluoroborates or tricyanofluoroborates. Fluorination of cyanohydridoborates is the third reaction type that includes direct fluorination with, for example, elemental fluorine, stepwise halogenation/fluorination reactions, and electrochemical fluorination (ECF) according to the Simons process. In addition, fluorination of [BH(CN)\(_{2}\){OC(O)Et}]\(^{-}\) to result in [BF(CN)\(_{2}\){OC(O)Et}]\(^{-}\) is described.},
