Synthesis and characterization of a cyclometallated palladium(II) complex with (2-diphenylphosphino)ethylamine

Abstract

Reaction of commercially available Ph₂PCH₂CH₂NH₂ with {PdCl(C₉H₁₂N)}₂ (2:1) in CH₂Cl₂ afforded, instead of Pd(Cl)(P-Ph₂PCH₂CH₂NH₂)(C₉H₁₂N) 1, the cationic complex [Pd(P,N-Ph₂PCH₂CH₂NH₂)(C₉H₁₂N)]Cl 2 which was characterized by single crystal X-ray crystallography. The lack of reactivity of 2 towards Rhodamine 6G can therefore be rationalized.
