Di-p-anisyl telluroxide

Di-p-anisyl telluroxide (typical procedure) Di-p-anisyltellurium dichloride (8.00 g, 23 mmol) is stirred at 95°C in 5% aqueous NaOH (100 mL) for 1 h. After cooling at 0°C the white solid is separated by filtration, washed with cold H2O (3X10 mL) and dried nnder vacnnm over P2O5 giving the telluroxide (5.60 g (81%) m.p. 187-189°C). [Pg.65]

Di-p-anisyl telluroxide (typical procedure) Di-p-anisyl telluride (0.80 g, 2.3 mmol) and Nal04 (0.50 g, 2.3 mmol) in CHjCN/MeOH/HjO (100 mL, 1 1 1) are heated under reflux for 2 h. The mixture is then cooled, treated with HjO (100 mL) and extracted with CHClj (3X30 mL). The extracts are evaporated and the residue chromatographed on Si02 (elution with CHClj/MeOH, 9 1). The crude product is recrystallized from benzene (0.26 g (22%) m.p. 189-191°C). [Pg.65]
