Diacetato-²O-bis[(S)-1-(4-fluorophenyl)ethylamine-N]palladium(II) and di--acetato-⁴O:O'-bis{[(S)-2-(1-aminoethyl)-5-fluorophenyl-²C¹,N]palladium(II)} benzene hemisolvate

Abstract: Complexes of the composition trans-[Pd(L)₂(OAc)₂] have been postulated as intermediates during cyclopalladation. The first structural characterization of such a precursor has now been achieved and its role in the reaction sequence has been established. Diacetato-²O-bis[(S)-1-(4-fluorophenyl)ethylamine-N]palladium(II), [Pd(O₂CMe)₂(4-FC₆H₃CHMeNH₂)₂] or [Pd(C₂H₃O₂)₂(C₈H₁₀FN)₂], (I), was obtained from palladium(II) acetate and (S)-NH₂CHMeC₆H₃F-4 in a 1:2 molar ratio. The intermediate was then reacted with additional palladium(II) acetate to give the acetate-bridged dinuclear complex di--acetato-⁴O:O'-bis{[(S)-2-(1-aminoethyl)-5-fluorophenyl-²C¹,N]palladium(II)} benzene hemisolvate, [Pd(4-FC₆H₃CHMeNH₂)₂(-O₂CMe)]₂·0.5C₆H₆ or [Pd₂(C₈H₉FN)₂(C₂H₃O₂)₂]·0.5C₆H₆, (II).

Formula: [Pd(C₂H₃O₂)₂(C₈H₁₀FN)₂] and [Pd₂(C₈H₉FN)₂(C₂H₃O₂)₂]·0.5C₆H₆
