2-Propen-1-yl 1,1,1-trifluoromethanesulfonate → 5-Methoxy-2-methyl-3-(2-propen-1-yl)benzotellurazolium Trifluoromethanesulfonate

Participants

Reaction Steps

5-Methoxy-2-methylbenzotellurazole (Example 20) (0.91 g, 0.033 mole), dissolved in dichloromethane (25 ml), was added at room temperature under a nitrogen atmosphere to the solution of 2-propen-1-yl trifluoromethanesulfonate (0.004 mole) from a dropping funnel. The mixture was stirred at room temperature for another 21 hours after the addition was complete, maintaining the nitrogen atmosphere. The solid was isolated by filtration, washed with diethyl ether, and dried at room temperature under vacuum. Yield 0.90 g.
