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.
