Treatment of sec-alkyl phenyl tellurides, except for the cyclohexyl system, with m-chloroperbenzoic acid(MCPBA) in diethyl ether readily afforded the corresponding olefins in good yields presumably via telluroxide elimination together with small amounts of alcohols and ketones. In the pri-alkyl and cyclohexyl cases the adducts between MCPBA and the tellurides were isolated as stable organotellurium(IV)
The conversion of phenyltelluroalkanes to haloalkanes was studied in connection with the homologation of alkyl halides. Similar reactions of 1,1-bis(phenyltelluro)alkanes provided a new synthetic method of aldehydes.

Oxidation of alkyl phenyl tellurides and telluroxides with meta-chloroperbenzoic acid in methanol at room temperature was accompanied by phenyl migration and ring-contraction respectively when applied to the compounds having phenyl group next to the tellurium moiety and to the methoxytelluration products of cyclic olefins.
