2-Propen-1-yl 1,1,1-trifluoromethanesulfonate → 2,5,6-Trimethyl-3-(2-propen-1-yl)benzotellurazolium Trifluoromethanesulfonate

Participants

Reaction Steps

To a solution of 2,5,6-trimethylbenzotellurazole (Example 22) (9.90 g, 0.0033 mole) in dichloromethane (30 ml) was added the solution of 2-propen-1-yl trifluoromethanesulfonate (0.004 mole) rapidly at room temperature under a nitrogen atmosphere, with good stirring. Solid began separating 10 minutes after the addition was complete. Stirring under a nitrogen atmosphere was continued for about 18 hours. The solid was isolated by filtration, washed with diethyl ether, and dried under vacuum at room temperature. Yield 1.0 g, m.p. 162°-164° C. The mass spectra agreed with the assigned structural formula.
