摘要：
A series of ruthenium(III)24 ami no fluo reneazo 1pheno late complexes with general formula [RuCl(PPh3)(2)(L1-5)] (1 5) (L = 2-(aminofluoreneazo)phenolate ligands) have been synthesized. The characterization of the synthesized complexes was accomplished by elemental analysis, spectroscopic (FT-IR, UV-Vis, Fluorescence and EPR) and ESI-MStechniques. The catalytic performance of one of the synthesized complexes 3 for the amidation of aldehyde in the presence of NaHCO3/NH2OH center dot HCl has been evaluated. The fluorescence emission of complexes [RuCl(PPh3)(2)(L-2)] (2) and [RuCl(PPh3)(2)(L-3) (3)] are effectively quenched by 1,4-benzoquinone and 1,4-naphthoquinone in acetonitrile medium.
