Tellurium tetrachloride (7.50 g, 28 mmol) and anisole (15 g, 139 mmol) were stirred at 180° for 18 h under a slow stream of nitrogen. After this time 48 mmol of hydrogen chloride had been evolved and the excess anisole was removed under high vacuum. The remaining brown solid was recrystallised from benzene to afford bis-(p-methoxyphenyl)tellurium dichloride (10.05 g, 88%), m.p. 181°-182° (lit., 181°-182°), δ(CDCl3) 8.01 (4H,d,J 9 Hz), 7.03 (4H,d,J 9 Hz) and 3.89 (6H,s).
