Abstract
Four trinuclear ruthenium carbonyl clusters, (6-BrPyCHRO)2Ru3(CO)8 (R = 4-OCH3C6H4, 1a; R = 4-BrC6H4, 1b) and (2-OC6H4-HC[double bond, length as m-dash]N-C6H4R)2Ru3(CO)8 (R = 4-OCH3, 2a; R = 4-Br, 2b), were synthesized from the reactions of Ru3(CO)12 with the corresponding N,O-bidentate ligands (two pyridyl alcohols and two Schiff bases) respectively in a ratio of 1 : 2. Three new complexes 1b, 2a and 2b have been fully characterized by elemental analysis, FT-IR, NMR and X-ray crystallography. The catalytic activity of these ruthenium complexes for the aerobic oxidation of primary benzylic amines to amides and nitriles in the presence of t-BuOK was investigated, of which the Schiff base complex 2a was found to exhibit the highest activity.

Abstract
Arylazoimidazole brings azoimine (-N=N-C=N-) chelating N(azo), N(imine) (abbreviated
- N, N/) centres and forms Ru(II) and Os(II) carbonyl complexes. These complexes act as catalysts
for the oxidation of alcohols to aldehydes/ketones by tertiary butyl hydro peroxide (ButOOH), hydrogen
peroxide (H2O2) and N-methylmorpholine-N-oxide (NMO) as oxygen sources. Different substituted
arylazoimidazoles such as 1-alkyl-2-(arylazo)imidazoles (RaaiR/), 1-alkyl-2-(naphthyl-α/β-
azo)imidazoles (α/β-NaiR) and (1-alkyl-2-{(o-thioalkyl)phenylazo}imidazole, SRaaiNR/) are used to
prepare Ru/Os-CO complexes. Ancillary ligands like hydride (H-), chloride (Cl-), triphenylphosphine
(PPh3) are used to monitor the catalytic efficiency of the complexes. Aromatic and aliphatic alcohols
like benzyl alcohol, 2-butanol, cyclopentanol, cyclohexanol, 1-phenylethanol, cinnamyl alcohol, diphenylmethanol,
are oxidized to the corresponding benzaldehyde, 2-butanone, cyclopentanone, cyclohexanone,
phenylacetone, cinamaldehyde, cyclopentanone, benzophenone, respectively. Different
physicochemical analyses (FT-IR, UV-Vis, Mass, NMR) suggest that the complexes react with an
oxidant to yield high valent ruthenium/osmium-oxo species (RuIV=O; OsIV=O), which is capable of
transferring the oxygen atom to alcohols. GC analysis accounts that percentage conversion order is as
follows : Cinnamyl alcohol > Cyclohexanol ~ 1-Phenylethanol > Diphenylmethanol > Cyclopentanol
> 2-Butanol > Benzyl alcohol. The oxidation efficiency of the oxidant follows the order : NMO >
ButOOH > H2O2. RuII complexes are more potent catalysts than OsII complexes. Out of three series
of RuII complexes, [RuCl(CO)(SMeaaiNEt)]ClO4 and [RuCl(CO)(SEtaaiNMe)]ClO4 showed highest
catalytic efficiency amongst 32 catalysts.

Abstract
Reaction of Ru3(CO)12 with two equiv of 6-bromopyridine alcohols 6-bromopyCHROH [(R = C6H5 (L1); R = 4-CH3C6H4 (L2); R = 4-OMeC6H4 (L3); R = 4-ClC6H4 (L4); (R = 4-CF3C6H4 (L5); R = 2-OMeC6H4 (L6); R = 2-CF3C6H4 (L7)] and 6-bromopyC(Me)2OH (L8) in refluxing xylene afforded novel trinuclear ruthenium complexes [6-bromopyCHRO]2Ru3(CO)8 (1a-1g) and [6-bromopyC(Me)2O]2Ru3(CO)8 (1h). These complexes were characterized by FT-IR and NMR spectroscopy as well as elemental analysis. The structures of all the complexes were further confirmed by X-ray crystallographic analysis. In the presence of tert-butyl hydroperoxide (TBHP) as the source of oxidant, complexes 1a-1h displayed high catalytic activities for oxidation of primary and secondary alcohols and most of oxidation reactions could be completed within 1 h at room temperature.
