remarkably different catalytic activity behavior, depending on the nature of the functional groups. Transfer hydrogenation of nitrobenzene with FA as a hydrogen source was probed using iridium complexes 3 or 4 as a catalyst. Under the same conditions, the analogous palladiumcomplex was found to be useful for the selective amidation of aniline with light carboxylic acids.
Several types of 1,8-diphenylanthracenederivatives were synthesized and their photophysical properties in the solid state were determined. A relatively high fluorescence quantum yield (ϕf = >0.83)...

A new protocol for palladium-catalyzed Buchwald-Hartwig amination of aryl chlorides and bromides with benzophenone imine as ammonia surrogate is described. The suggested reaction conditions are mild and may therefore be applied to a variety of sensitive starting materials.

We report the synthesis and characterization of four novel CCC—NHC pincer platinum(II) and palladium(II) complexes, which adopt a distorted square planar configuration. These complexes emit bright blue light in the solid state under UV irradiation with emissions that are stable in ambient atmosphere (O2 and H2O) for extended periods. We also report the synthesis and characterization of CCC—NHC pincer ligand nickel complexes, and solid state fluorescence spectra have been collected for two of the complexes reported. X-ray structural analysis of a representative compound exhibits a distorted square planar geometry. Finally, we report the synthesis and characterization of CCC—NHC pincer ligand complexes for abnormal carbens, triazole, and BIA.
