| Abstract: | [NMe4]TeCF3 is obtained in 60% yield from Me3SiCF3, elemental tellurium and [NMe4]F in glyme as a pale yellow solid decomposing at 185 °C. Cation exchange with [PNP]Br ([PNP] = bis(triphenylphosphoranylidene)ammonium) and [(dibenzo-18-crown-6)K]Br occurs spontaneously. These low co-ordinating cations increase significantly the nucleophilicity of the anion. |
