  to form a stable dianion on reduction. NMR spectra for the dianion [2]2− were recorded from solutions generated by reductions of 2 with alkali metals and compared with NMR spectra from reductions of 1,2-diphenyl-ortho-carborane 5. On the basis of observed and computed 11B NMR shifts, these nido-dianions contain bowl-shaped cluster geometries. The carborane is viewed as the electron-acceptor and the mesityl

• Fluoride-ion deboronation of p-fluorophenyl-ortho- and -meta-carboranes. NMR evidence for the new fluoroborate, HOBHF2−

  The reactions of 1-(4-fluorophenyl)-1,2-dicarbadodecaborane(12) 1 and 1-(4-fluorophenyl)-1,7-dicarbadodecaborane(12) 2 with tetrabutylammonium fluoride hydrate in tetrahydrofuran or acetonitrile have been monitored by F-19 and B-11 NMR. No carborane intermediates were observed prior to formation of the nido-anions 7-(4-FC6H4)-7,8-C2B9H11- 3 and 7-(4-FC6H4)-7,9-C2B9H11- 4 which each required two molecular proportions of fluoride and, by inference, one of water for complete reaction. The spectra of the initial anionic monoboron product of both reactions showed it to be the new fluoroborate HOBHF2- 5. The B-attached hydrogen atom of the fluoroborate 5 is derived from the starting carborane, since it was retained when Bu4NF.(D2O)(n) was used, but the nido-anions 3 and 4 bonded deuterium at the open face in this experiment. The H-1, B-11, F-19 and C-13 NMR spectra of carboranes 1-4 have been recorded and assigned. (C) 1997 Elsevier Science Ltd.
