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

Participants

Reaction Steps

A dried solution of 2-propen-1-yl tri-fluoromethanesulfonate (0.002 mole) in carbon tetrachloride was added dropwise to a solution of 5,6-dimethoxy-2-methylbenzotellurazole (Example 19) (0.50 g, 0.0016 mole) in dichloromethane (25 ml) under a nitrogen atmosphere at room temperature. After the addition was complete, stirring was continued for 7 hours. The solid was isolated by filtration, washed with diethyl ether, and dried at room temperature under vacuum. Yield 0.38 g. A mass spectrogram of the compound was in agreement with that expected for the structural formula.
