	abstract = {The hydrolytic stability of heteroaryltrifluoroborates under physiological conditions has been analyzed by F-19 NMR spectroscopy and is found to be greatly enhanced by the presence of endocyclic ring nitrogens. Stability is further enhanced by the presence of exocyclic electron withdrawing substituents. As with aryltrifluoroborates, NMR analysis suggests that the hydrolysis proceeds via single rate-determining step reflecting loss of the first fluoride atom. The stability of these complexes is significant both in terms of metal catalyzed cross-coupling reactions as well as the potential for generating boronic acid based F-18-PET imaging agents.

	abstract = {Solutions of SbF5 in HSO3F with x(SbF5) = 0.012 to 0.405 are studied by 500 MHz H-1 NMR (299 K) and 471 MHz F-19 NMR (213-250 K), using NMR tubes fitted with fluoropolymer lining. The initial process during dissolution is the fast solvolysis of monomeric SbF5 in HSO3F according to SbF5 + nHSO(3)F left arrow SbF5 - n(SO3F)(n) + nHF (n = 1, 2). All HF formed during solvolysis will no longer be removed by reaction with glass, but will remain in the superacid system. Besides participation in the fast formation of various fluoro-fluorosulfato anions [SbF6 - n(SO3F)(n)](-) (n = 0, 1, 2) and acidium ions [H2X](+)((solv.)) (X= F, SO3F), HF is involved in slow-exchange reactions of the type [SbF6 - n(SO3F)(n)](-)((solv.)) + HF left arrow [SbF7 - n(SO3F)(n- 1)](-)((solv.)) + HSO3F (n = 1, 2) detected because of a delay of 3 months between sample preparation and measurements and confirmed by repeating theses measurements after a further 3 months. There are three notable differences to our earlier study, affecting concentrations of the fluoro-fluorosulfato antimonate anions observed: (i) in dilute solutions [SbF6](-) is formed in high concentrations (34.7-76.1\%), with [Sb2F11](-) now clearly detected at intermediate to high SbF5 concentrations (up to 5.8\%); (ii) bis-fluorosulfato anions (cis-, trans-[SbF4(SO3F)(2)](-)) are found in much lower concentrations only, which decrease further with time, while tris-fluorosulfato anions ([SbF3(SO3F)(3)](-)) are now no longer observed; (iii) these reduced concentrations of poly-fluorosulfato anions in dilute solutions are responsible for the formation of fewer mu-SO3F-oligomers at lower concentrations, when more SbF5 is added. As a consequence, the HSO3F-SbF5 magic acid system is now less complex than found previously and only seven anionic species are clearly observed.},

	abstract = {The synthesis of [Au(PF3)(2)][Sb2F11], the first trample of a linear, thermally stable metal bis(trifluorophosphine) complex is achieved by CO substitution of [Au(CO)(2)][Sb2F11] by PF3. The [A(PF3)(2)](+) cation can also be generated by reductive phosphorylation by an excess of PF3 in fluorosulfuric acid. Spectroscopic characterization involves F-19 and P-31 NMR in HSO3F and SO2 solution including spectral simulation by the WIN-DAISY method and FT-IR and Raman spectra. Spectroscopic evidence suggests that the metal-ligand bond involves predominantly sigma-bonding with drastically reduced pi-back-donation.},
