The reactions of aryltellurium oxochlorides with the lowest aliphatic acid anhydrides lead to diaryltellurium dichlorides, Te, and CO2 through the intermediate formation of diaryltellurium chloride diacylates.Aryltellurium trichlorides and carboxylic acid anhydrides are formed in the reaction with acyl chlorides.The chlorine atom in the tellurium oxochlorides is replaced by a phenyl group on reaction with phenyllithium.The reaction with dimedone in the presence of triethylamine leads to diaryl ditellurides and a product of trimerization of a carbene, viz., a dimedone derivative that is formed in the thermal decomposition of the intermediate ylid.
