New Ru(II) complexes containing tris(2-pyridylmethyl)amine. Synthesis, structural, CT-DNA/albumin interaction, anti-oxidant and cytotoxicity studies
Two new Ru(II) complexes containing tris(2-pyridylmethyl)amine was synthesised by reacting [RuCl2 (EPh3)3] E = P, As with TPA.3HClO4 in 1:1 ratio. The new complexes were characterized by various spectroscopic (I
Four palladium(ii) complexes with tripodal ligands of the tpa family (tpa = tris(2-pyridylmethyl)amine) have been synthesized and X-ray characterized. These complexes efficiently catalyze benzylic C-H oxidation of various substrates with peracetic acid, affording the corresponding ketones in high yields (up to 100%), at 1 mol% catalyst loadings. Complex [(tpa)Pd(OAc)](PF6) with the least sterically demanding ligand tpa demonstrates the highest substrate conversions and ketone selectivities. Preliminary mechanistic data provide evidence in favor of metal complex-mediated rate-limiting benzylic C-H bond cleavage by an electron-deficient oxidant.
