Barium complexes ligated by bulky boryloxides [OBR2]? (where R=CH(SiMe3)2, 2,4,6-iPr3-C6H2 or 2,4,6-(CF3)3-C6H2), siloxide
Synthesis and characterisation of some new boron compounds containing the 2,4,6-(CF3)3C6 H2 (fluoromes = Ar), 2,6-(CF3)2C6H3 (fluoroxyl = Ar′), or 2,4-(CF3)2 C6H3 (Ar″) ligands

Several new boron compounds containing the 2,4,6- (CF3)3C6H2 (fluoromes = Ar), 2,6-(CF3)2C6H3 (fluoroxyl = Ar′) or 2,4-(CF3)2C6H3 (Ar″) ligands have been synthesised from reactions of ArLi, Ar′Li or Ar″Li with BCl3, and characterised by 19F and 11B NMR spectroscopy. Chlorine/fluorine exchanges are evident in these reactions. The crystal and molecular structures of Ar2BF, Ar″3B, Ar2B(OH), Ar′B(OH)2 and Mes2BF (Mes = 2,4,6-Me3C6H2) have been determined by single crystal X-ray diffraction. Ar″3B represents the first example of a compound containing three Ar″ ligands to be structurally characterised. Molecular geometries and GIAO-NMR shifts for several new boron compounds have been calculated at the HF/6-31G* level of theory, and compared with the available experimental results.

Treatment of the new boronous acid HOB (fmes)2 (1) (fmes = 2,4,6-(CF3)3C6H2) with n-butyllithium in diethyl ether/pentane affords after work-up the dimer [Li(thf)OB(fmes)2]2 (2). Reaction of [Mo2(NMe2)6] with two equivalents of 1 in toluene gives the amido-boroxide complex Mo2(NMe2)4[OB(fmes)2]2 (3). Treatment of CuBr2 with LiOB(Mes)2 (mes = 2,4,6-Me3C6H2) in tetrahydrofuran affords after work-up and addition of excess pyridine the monomeric copper(II) boroxide {Cu[O3B2(mes)2]2[Li(CH 3CN)(C5H5N)]2} (4), containing the new ligand mesB(O)OB(O)mes, as a result of loss of mesitylene and formation of a B-O-B bond. 2 and 4 have been structurally characterized.
