Halfsandwichruthenium(II) complexes were synthesized from [RuCl2(η6-p-cymene)]2 and N-substituted benzimidazole. All new compounds were characterized by elemental analysis, 1H NMR, 13C NMR, and IR spectroscopy. Aminoarenes were readily converted into secondary amines by the reaction at 150 °C with benzyl alcohol and in the presence of a catalytic amount of novel rutheniumcomplexes. All of [RuCl

geometry around Pd is distorted square planar. The Pd-NHC complexes were efficient catalysts for the direct C5-arylation of 2-n-butylthiazole, 2-n-butylfuran, and 2-n-butylthiophene with various aryl-bromides and showed high catalytic activity for arylation reaction using only 1 mol% catalystloading at 130 °C for 1 h. The conversions for substrates containing electron-withdrawing groups were higher

13C NMR spectroscopy, LC–MS, and elemental analysis. The compounds were used for their antioxidant capacity by commercial kit assay. Further, these were screened for their cytotoxic effect against cell lines including MCF-7, A-549, and L929 using cisplatin as a reference drug. It resulted that the total antioxidant capacity values of the compounds were found to be quite low compared to the trolox equivalent
