Abstract
The reactivity of the bis(acyl)phosphide ion [P(COR)(2)](-) (BAP(-), R=Ph, Mes) with silicon halides SiX4 (X=Cl, Br) and pnictogen chlorides ECl3 (E=As, Sb and Bi) was investigated. The reaction with SiX4 leads to the hexacoordinate silanes SiX2(BAP)(2) in which BAP(-) is coordinated in the chelating kappa(2)-O,O ' mode, analogously to acac(-). Unexpectedly, the coordination behaviour of BAP(-) differs from the one of acac(-) in the interpnictogen compounds E(BAP)(3) (E=As, Sb) in which the formation of E-P bonds is favoured over kappa(2)-O,O ' chelation via the oxygen centres. Finally, the reaction of BiCl3 with three equivalents of Na(BAP) leads to the formation of red, crystalline Bi-2(BAP)(4), an air stable dibismuthine, as product of a redox reaction.
