    Description / Table of Contents: Properties and Reactions of Tris(2,6-difluorophenyl)bismuth(III) and Tris(2,6-difluorophenyl)bismuth(V) Derivatives(2,6-F2C6H3)3BiF2 and (2,6-F2C6H3)3BiCl2 are prepared oxidizing (2,6-F2C6H3)3Bi with XeF2 or Cl2 respectively, while direct fluorination effect the oxidation of the aromatic system. The reaction of (2,6-F2C6H3)3BiCl2 With (CH3)3SiCl yields (2,6-F2C6H3)3BiCl2. Attempts to oxidize (2,6-F2C6H3)3Bi with Br2, I2 and ICl give (2,6-F2C6H3)X and BiX′3 (X = Br, I; X′ = Cl, Br, I). The rection of (2,6-F2C6H3)3Bi with IF5 gives BiF3 and (2,6-F2C6H3)IF4. (2,6-F2C6H3)3Bi(OCOCF3)2 and (2,6-F2C6H3)3Bi(OSO2CF3)2 are formed via ligand exchange rection of (2,6-F2C6H3)3BiF2 with (CH3)3SiOR or of (2,6-F2C6H3)3BiCl2 with AgOR (R = COCF3, SO2CF3). The preparations and properties of the new compounds are described. (2,6-F2C6H3)3Sb and (2,6-F2C6H3)2Te are prepared by the transmetalation reactions of (2,6-F2C6H3)3Bi with Sb and Te.
    Notes: (2,6-F2C6H3)3 BiF2und(2,6-F2C6H3)3BiCl2 werden durch Oxidation von (2,6-F2C6H3)3 Bi mit XeF2 bzw. Cl2 dargestellt, während die Direktfluorierung zu einer Oxidation des aromatischen Systems führt, (2,6-F2C6H3)3BiCl2 wird auch durch die Umsetzung von (2,6-F2C6H3)3 BiF2 mit (CH3)3SiCl erhalten. Oxidationsversuche von (2,6-F2C6H3)3Bi mit Br2, I2 und ICl ergeben (2,6-F2C6H3)X und BiX′3 (X = Br, I; X′ = Cl, Br, I). Die Umsetzung von (2,6-F2C6H3)3Bi mit IF5 führt zur Bildung von BiF3 und (2,6-F2C6H3)IF4. (2,6-F2C6H3)3Bi(OCOCF3)2 bzw. (2,6-F2C6H3)3Bi(OSO2CF3)2 werden durch Ligandenaustauschreaktionen von (2,6-F2C6H3)3BiF2 mit (CH3)3SiOR oder von (2,6-F2C6H3)3BiCl2 mit AgOR gebildet (R COCF3, SO2CF3). Die Syntheseverfahren und Eigenschaften der neuen Verbindungen werden beschrieben. Durch Transmetallierungsreaktionen von (2,6-F2C6H3)3Bi mit Te und Sb werden (2,6-F2C6H3)3Sb und (2,6-F2C6H3)2Te dargestellt.

    Description / Table of Contents: Syntheses and Properties of Some New Tris(fluorophenyl)antimony and -bismuth Compounds. Crystal Structure of Tris(2,6-difluorophenyl)bismuth(2,6-F2C6H3)3Bi, (2,4,6-F3C6H2)3Bi, and (2,6-F2C6H3)3Sb are prepared via Grignard reactions with BiBr3 and SbBr3, respectively. The syntheses and properties of the new compounds and the crystal structure of (2,6-F2C6H3)3Bi are described. From the reaction of BiBr3 with Ag(OCOC6H3F2) the bismuth benzoate Bi(OCOC6H3F2)3 is formed in 83% yield. Attempts to prepare (2,6-F2C6H3)3Bi by decarboxylation of the bismuth benzoate failed.
    Notes: (2,6-F2C6H3)3Bi, (2,4,6-F3C6H2)3Bi und (2,6-F2C6H3)3Sb werden durch Grignard-Reaktionen mit BiBr3 bzw. SbBr3 dargestellt. Die Synthesebedingungen und die Eigenschaften der neuen Verbindungen sowie die Kristallstruktur von (2,6-F2C6H3)3Bi werden beschrieben. Bi(OCOC6H3F2)3 entsteht in 83% Ausbeute aus BiBr3 und Ag(OCOC6H3F2); die präparative Darstellung von (2,6-F2C6H3)3Bi durch Decarboxylierung des Bismutbenzoats gelingt nicht.
