Tellurium tetrachloride (11.36 g, 0.042 mol) and methyl phenoxy acetate (21.00 g, 0.127 mol) were refluxed in carbon tetrachloride (175 ml) for 18 h. The reaction solution was filtered while still hot, the filtrate cooled in an ice bath and the resulting solid filtered to afford p-methoxycarbonylmethoxyphenyltellurium trichloride (16.11 g, 96%) δ(CDCl3 /DMSO d6) 8.38 (2H,d,9Hz), 6.90 (2H,d,9 Hz), 4.67 (2H,s), and 3.77 (3H,s). No attempt was made to purify this compound and it was used directly in the next step.
