2-methoxycyclohexyl phenyl

When /ran.v-2-methoxycyclohexyl phenyl tellurium was treated with 2 molar equivalents of sodium periodate in aqueous methanol, formylcyclopentane was isolated in 75% yield. /ram-2-Methoxycycloheptyl phenyl tellurium and an excess of sodium periodate, hydrogen peroxide, or /er/.-butyl hydroperoxide in aqueous methanol produced mixtures of the dimethyl acetal of formylcyclohexane, cyclohexylformaldehyde, and methoxy-2-cyclo-heptene3. 

Treatment of 2-methoxycyclohexyl phenyl tellurium oxide, prepared from cyclohexene and phenyl tellurium tribromide in methanol followed by hydrolysis of the tellurium dibromide, with 3-chloroperoxybenzoic acid in methanol caused ring contraction with formation of the dimethyl acetal of cyclopentanecarbaldehyde1,2. 

Addition of aryl tellurium trihalides to cyclohexene produces rra 5-l-aryldihalotelluro-2-halocyclohexanes when the reactions are carried out in chloroform, and trans- -aryldihalotelluro-2-methoxycyclohexanes when methanol is used as the reaction medium. Treatment of the 2-chlorocyclohexyl 4-methoxyphenyl tellurium dichloride with ter/.-butyl hydroperoxide in acetic acid yielded trani-l,2-dichlorocyclohexane and aryl chloride. Bis[4-methoxyphenyl] tellurium dichloride did not yield any aryl chloride under these conditions. Pyrolysis of tra .s-2-methoxycyclohexyl phenyl tellurium dibromide afforded trans-1 -bromo-2-methoxycyclohexane. ...
