Popis: [NMe 4 ]TeCF 3 is obtained in 60% yield from Me 3 SiCF 3 , elemental tellurium and [NMe 4 ]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.
