Abstract

Reaction of H₃M·NMe₃, M = Al or Ga, with 1,1,1,5,5,5-hexafluoropentane-2,4-dione resulted in metallation/reduction, M = Al, or reduction, M = Ga, of the β-diketone, both products being isolated as binuclear species, [Al₂{OC(CF₃)=CHCH(CF₃)O}₃(NMe ₃)₂] (structurally authenticated for the RRS/SSR diastereoisomer), and [Ga₂{rac-OCH(CF₃)CH₂CH(CF₃)O} ₃(NMe₃)₂] (D₃ symmetry) containing five- or four-co-ordinate metal centres respectively; pentane-2,4-dione, 1,1,1-trifluoropentane-2,4-dione and 2,2,6,6-tetramethylheptane-3,5-dione afford exclusively metallation products, isolated as the tris(β-diketonato)metal(III) complexes.
