Detellurative carbonylation of aryltellurium trichloride NiiCO) method (typical procedure). Ni(CO)4 (2.6 mL, 20 mmol) is added to p-methoxyphenyltellurium trichloride (2.0 g,... 

Detellurative carbonylation of diary It ellurium dichlorides (typical procedure) Following the above procednre, Ni(CO)4 (1.5 mL, 11.5 mmol) and di-p-methoxyphenyl-tellurium dichloride (2.0 g, 4.8 mmol) furnish p-Me0CgH4C02H (1.05 g (71%)), (p-MeOCgH4)2Te (0.25 g (15%)) and a trace amount of (p-MeOCgH4)2CO. 

Carboxylic acids are also produced through the detellurative carbonylation of several types of telluride by treatment with carbon monoxide at atmospheric pressure and room temperature in the presence of Pd(ll) salts, in various solvents. ...
