Dodecyl 4-methoxyphenyl

Little has so far been reported on the chemistry of teUurones. The preparation of several dialkyl tellurones by H2O2 or air oxidation of the corresponding tellurides or telluroxides has been claimed, but it is doubtful whether those compounds were isolated in a pure tellurone form. In 1982 the first definitely characterized tellurone, bis(4-methoxyphenyl) tellurone (60), was prepared by periodate oxidation of the corresponding telluroxide (59 equation 50). Both (59) and (60) woric as mild useful oxidants which show some chemoselectivities and readily oxidize thiols to disulfides. The preparation of dodecyl 4-methoxyphenyl tellurone by a similar method has also been claimed. ... 

The resulting reaction solution was poured into 200 ml of ice water, and the toluene phase was separated off and washed twice with water. The required amount of hydrochloric acid was added to the toluene solution, the toluene was distilled off under reduced pressure and the residue, which remained was recrystallized from acetone to give l,7-bis-(2-methoxyphenyl)-3-methylaza-7-cyanononadecane hydrochloride or a-dodecyl-3-methoxy-a-[3-[[2-(3-methoxyphenyl)ethyl] methyl amino] propyl] benzene-acetonitrile (anipamil) ... 

Oxidation of 4-methoxyphenyl dodecyl tellurium with tert- butyl hypochlorite in benzene gave a 1 2 1 mixture of the diorgano tellurium, its oxide, and its dioxide3. 

Refluxing a toluene solution of 4-methylphenyl dodecyl tellurium dioxide for 40 h produced 1-dodecene (50% yield), 1-dodecanol (15%), and tetracosane3. Bis[4-methoxyphenyl] tellurium dioxide was reduced by hydrazine hydrate in methanol to bis[4-methoxyphenyl] tellurium1.
