Formation of bis(2-pyridylcarbonyl)aminate by oxidation of ethylbis(2-pyridylmethyl)amine on the trichloridoruthenium(iii) complex

Abstract

Oxidation of the facial-type trichloridoruthenium(III) complex bearing ethylbis(2-pyridyl-methyl)amine (ebpma), fac-[Ru^IIICl₃(ebpma)], with an equimolecular amount of (NH₄)₂[Ce^IV(NO₃)₆] in acetonitrile afforded a ligand-based oxidation product of an acetonitriledichloridoruthenium(III) complex having bis(2-pyridylcarbonyl)aminato (bpca), [Ru^IIICl₂(NCCH₃)(bpca)]. The complex changed into a trichloridoruthenium(III) complex by a reaction with hydrochloric acid and the triacetonitrileruthenium(II) complex by reduction with Zn in ethanol–acetonitrile. The bpca moiety showed interactions with cations such as protons.
