Procedure: 5,6-Dimethoxy-2-methylbenzotellurazole (Example 19) (1.0 g, 0.033 mole) was dissolved in dichloromethane (25 ml). The solution of 2-propyn-1-yl trifluoromethanesulfonate, prepared as described above, was added from a dropping funnel under a nitrogen atmosphere. After completion of the addition the mixture was stirred for 16 hours at room temperature. The solid was isolated by filtration, washed with diethyl ether, and dried under vacuum at room temperature. Yield, 1.14 g (70% of theory). The infrared, nuclear magnetic resonance, and mass spectra were in agreement with that expected for the structural formula. was added from a dropping funnel under a nitrogen atmosphere After completion of the addition the mixture The solid was isolated by filtration washed with diethyl ether dried under vacuum at room temperature Yield

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-Methylbenzotellurazole (Example 18) (0.81 g, 0.0033 mole) was dissolved in dichloromethane (30 ml). A solution in carbon tetrachloride (25 ml) of 2-propyn-1-yl trifluoromethanesulfonate, prepared as described above, (0.004 mole) was placed in a dropping funnel and added at room temperature under a nitrogen atmosphere to the benzotellurazole solution. The mixture was stirred for about 20 hours after the addition was complete, forming a white solid, which was isolated by filtration, washed with dichloromethane, and dried at room temperature under vacuum. Yield 0.60 g (42% of theory), m.p. 150°-152° C. The infrared, nuclear magnetic resonance and mass spectra were consistent with the structural formula. was placed in a dropping funnel after the addition forming a white solid which was isolated by filtration washed with dichloromethane dried at room temperature under vacuum
