An indole hydrazone has successfully been synthesized employing Schiff base reaction conditions starting from 4,6-dimethoxy-2,3-diphenylindole-7-carbaldehyde with hydrazine hydrate. The of this compound acetone yielded based imine compound. structure targeted was identified by mass and 1H spectroscopy along single crystal X-ray diffraction technique. Also, bromination bis-indole N-bromo succini...

We report a synthesis of 3-bromo-9-N′-(N,N-dimethylformamidino)benzanthrone in good yield by condensation reaction 3-bromo-9-aminobenzanthrone with dimethylformamide the presence phosphorous oxychloride. The structure synthesized amidine was characterized FTIR-ATR, NMR experiments, and elemental analysis. title compound analyzed UV-Vis fluorescence spectroscopy various organic solvents.

A set of new chromium(III) [Cr(III)] complexes based on the tridentate ligand HC(Pz)2Py (Pz = pyrazole; Py = pyridine) and its derivatives were prepared, characterized, and evaluated for ethylene polymerization/oligomerization. X-ray single-crystal analyses of the Cr(III) complexes showed tridentate coordination on the fac-octahedral Cr sphere. Upon activation with methylaluminoxane (MAO), the ...

2D spectrally resolved ultrafast (<200 fs) IR vibrational echo experiments were performed on Rh(CO)(2)acac [(acetylacetonato)dicarbonylrhodium (I)]. The 2D spectra display features that reflect the 0-1 and 1-2 transitions and the combination band transition of the symmetric (S) and antisymmetric (A) CO stretching modes. Three oscillations in the data arise from the frequency difference between ...

The ligand 2-(acetylacetonato)-iminobenzohydroxamic acid and its different mixed ligand novel complexes with NiII having specific formulae have been synthesized and characterised by elemental analyses, magnetic and conductance measurements, IR and electronic spectral studies. The ligand was found to behave in dibasic tetradentate (OO’ NO donor) manner. All the synthesized NiII complexes were no...
