Methyl triflate → HCID 13931236, compound

Participants

Reaction Steps

2-Methylnaphtho[1,2-d]tellurazole (Example 26) (14.8 g=0.05 mole) was dissolved in dry dichloromethane, and methyl trifluoromethanesulfonate (5.52 ml=0.05 mole) was added. The flask was sealed and kept over a weekend. Pale yellow plates (16.1 g, 70% of theory) formed. The product was recrystallized from 150 ml of acetone by addition of diethyl ether (m.p. 178°-183° C.). The mass and nuclear magnetic resonance spectra were in agreement with that expected for the structural formula.
