Product 1

HCID 143241492,5,6-Trimethyl-3-(2-propyn-1-yl)benzotellurazolium Trifluoromethanesulfonate

Procedure

This compound was prepared in the same way and on the same molar scale as the compound of Example 46, except that 2,5,6-trimethylbenzotellurazole (Example 22) was used in place of 5,6-dimethoxy-2-methylbenzotellurazole. Yield 1.10 g (72% of theory) cream colored powder, m.p. 189°-192° C. dec. The infrared, nuclear magnetic resonance, and mass spectra were in agreement with that expected for the structural formula.
