PROPERTIES AND REACTIONS OF TRIS(2,6-DIFL UOROPHENYL)BISMUTH(III) ANDTRIS(2,6-DIFLUOROPHENYL)BISMUTH(V) DERIVATIVES

(2,6-F2C6H3)(3)BiF2 and (2,6-F3C6H3)(3)BiCl2 are pre pared oxidizing ( 2,6-F2C6H3)(3)Bi with XeF2 or Cl-2, respectively, while direct fluorin ation effects the oxidation of the aromatic system. The reaction of (2 ,6-F2C6H3)(3)BiF2 with (CH3)(3)SiCl yields (2,6-F2C6H3)(3)BiCl2. Attem pts to oxidize (2,6-F2C6H3)(3)Bi with Br-2, I-2, and ICl give (2,6-F2C 6H3)X and BiX'(3) (X = Br, I; X' = Cl, Br, I). The reaction of (2,6-F2 C6H3)(3)Bi with IFS gives BiF3 and (2,6-F2C6H3)IF4. (2,6-F2C6H3)(3)Bi( OCOCF3)(2) and (2,6-F2C6H3)(3)Bi(OSO2CF3)(2) are formed via ligand exc hange reactions of (2,6-F2C6H3)(3)BiF2 with (CH3)(3)SiOR or of (2,6-F2 C6H3)(3)BiCl2 with AgOR (R = COCF3, SO2CF3). The preparations and prop erties of the new compounds are described. (2,6-F2C6H3)(3)Sb and (2,6- F2C6H3)(2)Te are prepared by the transmetalation reactions of (2,6-F2C 6H3)(3)Bi with Sb and Te.
