Characterization of reaction products of 2-thienylamine and 2-furfurylamine with bis(acetylacetonato)palladium(II)

Abstract

2-Thienylamine (Hata) and 2-furfurylamine (Hafa) reacted with bis(acetylacetonato)palladium(II) [Pd(acac) 2] in dichloromethane at room temperature to give Pd(acac) 2(Hata) and Pd(acac) 2(Hafa), respectively. In refluxing toluene the former amine gave [Pd(acac)(ata)] 2, while with the latter no further reaction took place. In Pd(acac) 2(Hata) and Pd(acac) 2(Hafa) the amines were coordinated through the amino group, with one acac ligand as an OO chelate and the other γ-carbon bonded. X-ray analysis revealed that [Pd(acac)(ata)] 2 was a dimer where the palladium atoms were bridged by deprotonated amino groups and coordinated with OO chelating acac ligands.
