Synthesis, structure, catalytic transfer hydrogenation and biological activity of cyclometallated ruthenium(III)2-(arylazo)phenolate complexes

Immobilization of a cationic ruthenium(II) complex containing the hemilabile phosphaallyl ligand in hexagonal mesoporous silica (HMS) and application of this material as hydrogenation catalyst

“…5a) [12]. The sample obtained by cation exchange of hexafluorophosphate salt of (1) with HMS(Si/Al = 40) support shows a UV-Vis band with the same k max , which confirms that immobilization of the cationic ruthenium(II) complex (1) does occur (Fig.…”

Ruthenium(II) mediated C–H activation of substituted acetophenone thiosemicarbazones: Synthesis, structural characterization, luminescence and electrochemical properties

“…In continuation of our research on the synthesis of ruthenium cyclometalated complexes via direct C-H activation of azo or thiosemicarbazone ligands [38][39][40][41][42], we describe here the cyclometalation of ruthenium(II) with 4 0 -substituted acetophenone thiosemicarbazone ligands incorporated with triphenylarsine as ancillary ligand. All the complexes have been characterized by analytical and spectral methods.…”

Ruthenium(III) mediated C–H activation of azonaphthol: Synthesis, structural characterization and transfer hydrogenation of ketones

“…Cyclometalated compounds show important applications, such as their use in regiospecific organic and organometallic reactions [9], insertion reactions [10], the synthesis of new metal mesogenic compounds [11] and in biologically active compounds [12]. Even though a number of reports are known for cyclometalated ruthenium(II) complexes [13][14][15], only very little has been covered on cyclometalated ruthenium(III) complexes [16][17][18][19] II in the literature including our recent reports.…”
