The bis-(p-methoxyphenyl)tellurium dichloride (8.00 g, 19.4 mmol) was stirred at 95° in aqueous sodium hydroxide (100 ml, 5%) for 1 h. After cooling in an ice bath the white solid was filtered and dried under vacuum over phosphorus pentoxide to give bis-(p-methoxyphenyl)telluroxide (5.60 g, 81%), m.p. 187°-189° (lit., 190°-191°) νmax (Nujol) 1585,1575,1490,1460,1401,1380,1295,1247,1180,1172,1109,1068,1026,823,811 and 789 cm-1.
