The dried solution of 2-propen-1-yl trifluoromethanesulfonate (0.008 mole) in carbon tetrachloride was placed in a dropping funnel and added to a solution of 2-methylbenzotellurazole (Example 18) (1.62 g, 0.0066 mole) in dichloromethane (25 ml) under a nitrogen atmosphere at room temperature. After the addition was complete, stirring was continued for 18 hours. The solid was isolated by filtration, washed with diethyl ether, and dried at room temperature under vacuum. Yield 0.43 g (15%), m.p. 90°-93° C. Infrared, nuclear magnetic resonance, and mass spectra were in agreement with that expected for the structural formula.
