Chemistry of ruthenium with some phenolic ligands: synthesis, structure and redox properties

“…These isomers have been prepared by following the above procedures (Section 2.2.4). In method A, HL 3 was used instead of HL 1 . The ctc and ccc isomers of [Ru(PPh 3 ) 2 (L 3 ) 2 ] were obtained in 32 and 36% yields.…”

“…The ctc and ccc isomers of [Ru(PPh 3 ) 2 (L 3 ) 2 ] were obtained in 32 and 36% yields. In method B, [Ru(PPh 3 ) 2 (L 3 )Cl 2 ] and HL 1 were used instead of [Ru(PPh 3 ) 2 (L 1 )Cl 2 ] and HL 1 , respectively. Yields of the ctc and ccc isomers were 32 and 34%, respectively.…”

“…Magnetic susceptibilities were measured using a PAR 155 Vibrating sample magnetometer fitted with a Walker scientific L75FBAL magnet. 1 H NMR spectra were recorded on a Bruker AC-200 spectrometer using TMS as the internal standard. ESR spectra were recorded on a Varian Model 109C E-line X-band spectrometer fitted with a quartz Dewar for measurements at 77 K (liquid dinitrogen).…”

Catalytic and antimicrobial studies of binuclear ruthenium(III) complexes containing bis-β-diketones

“…The interest in coordination complexes of ruthenium stems from their versatile electron-and energy-transfer properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. As a result these complexes exhibit a wide range of reactivities.…”

Chemistry of some ruthenium phenolates: synthesis, structure and redox properties

“…There is much current interest in the chemistry of ruthenium [1][2][3][4][5][6][7][8][9][10], most of which is due to the fascinating electron-transfer and energy-transfer properties displayed by the complexes of this metal. The coordination environment around the metal primarily dictates properties of the ruthenium complexes.…”
