実験手順
5,6-Dimethoxy-2-methylbenzotellurazolium chloride (Example 12) (10 g) was ground with an equal quantity of sodium bicarbonate and a little water in a mortar until evolution of carbon dioxide ceased. The product was collected by filtration, washed with water and dried in a vacuum to yield ≃8.5 g of colorless powder, m.p. 78°-80° C. Slow crystallization from cyclohexane yielded well defined prisms, m.p. 80°-83° C. The mass spectra and nuclear magnetic resonance spectra were in agreement with that expected for the structural formula.
