A new class of cyclic telluronium salt was prepared. Conductivity measurements of a range of these in DMSO and DMF show that considerable ion pairing occurs in solution. The compounds show stability toward the reductive elimination of alkyl halides in solutions such as CHC1
3, DMSO and DMF. The idea of association of the telluronium salts is now firmly established, and is supported by mass spectral and molecular weight data. 1
H,
125Te and
13C NMR spectral data are presented. The
125te chemical shifts for the telluronium salts are measured in solvents with different polarity and are shown to correlate with the nature of the alkyl group and with the electronegativity of the anion substituent...
