Abstract

Three new boron complexes with anilido-imine ligands, ortho-C6H4(NAr1)(CH=NAr2)BF2 [Ar1 = 2,6-Et2C6H3, Ar2 = p-MeC6H4 (3a); Ar1 = 2,6-iPr2C6H3, Ar2 = p-MeC6H4 (3b); Ar1 = 2,6-iPr2C6H3, Ar2 = 2,6-Me2C6H3 (3c)] were synthesized by the reaction of BF3(OEt2) with the lithium salt of the corresponding ligands. All complexes were characterized by 1H, 11B, 13C and 19F NMR spectroscopy, elemental analyses and mass spectrometry. The molecular structures of complexes 3a3c were determined by X-ray crystallography. DSC analysis of 3a3c demonstrates their good thermal stability. Luminescent properties of the ligands and the complexes 3a3c in solution and the solid state were studied. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
