1,2-Dimethoxybenzene (veratrole, 13.8 g=0.1 mole) and tellurium tetrachloride (26.9 g=0.1 mole) were heated in chloroform (120 ml) for 2 hours under reflux and with stirring. After 30 minutes yellow crystals started to precipitate. The product (25.2 g, 67.9% of theory) was collected by filtration and dried in a vacuum oven, m.p. 162°-163° C. (dec. with gas evolution). The mass spectra were in agreement with that of the structural formula.
