Abstract

The reactivity of a range of 2-arsa- and 2-stiba-dionato lithium complexes, [{(solv)Li{E[C(O)R]₂}}₂], E = As or Sb, R = alkyl or aryl, toward a variety of Group 8–12 transition metal complexes has been examined. The heterodionate ligands in the generated complexes have displayed a variety of coordination modes which in many cases have been confirmed by X-ray crystallographic studies. Modes that were encountered were η¹⁻As or Sb in [(C₅Me₅)Fe(CO)₂{As[C(O)Ph]₂}], trans-[PtCl(PEt₃)₂{As[C(O)Ph]₂}] and trans-[PtCl(PEt₃)₂{Sb[C(O)(C₂H₂Me₃-2,4,6)]₂}]; η²-O,O in [M{As[C(O)But]2}2(DME)] M = Fe or Co and [RuCl2(PPh3)2{As[C(O)But]2}]; η1-As ∶ η1-O ∶ η2-CO in [RuCl(PPh₃)2{As[C(O)Buᵗ]₂}] and η¹-As ∶ η²-O,O in [Zn{As[C(O)Buᵗ]₂[LiCl(DME)]}₂]. The syntheses of a number of related complexes are reported, as is the preparation and structural characterisation of the tetraacyldiarsane, [As{C(O)Ph}₂]₂.
