    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.
